Added

• ROOT support: a unified privilege layer with three modes — ROOT / Shizuku / Normal. Root detection does not check whether a su binary exists; it actually runs su -c id and looks for uid=0, so "su installed but not granted" and fake root are never misdetected.
• Execution mode selector: a new "Execution mode" row in Settings that expands in place (no pop-up): Auto / ROOT / Shizuku / Normal. Choosing ROOT on a device without root falls back to Shizuku, then to Normal, with a toast telling you what actually took effect.
• Custom su command template: you can change the su -c {cmd} form to match Magisk / KernelSU / modified su. Three presets are included (su -c, su -0 -c, su --mount-master -c); tapping one runs a real test immediately and tells you whether it works. A template must contain {cmd} to be saved.
• "App internal" path: the path picker now offers /data/user/0/<package>/games/com.mojang/minecraftWorlds/ — Minecraft's actual private directory. It is only shown when real root is available, and re-tested every time the picker opens.
• Write-back now uses atomic replacement: new data is fully staged in a temp directory on the same partition, the original is renamed aside, the new one takes its place, and only then is the old copy removed; any failure rolls back immediately. A self-check (CURRENT must exist, no nested folders) rolls back automatically on anomalies.
• World thumbnails actually appear: the standard path lives under Android/data, where Android 11+ scoped storage makes direct reads fail, so the three tiles used to stay grey forever. Bytes are now streamed through the privilege channel and decoded in memory, never touching disk.
• Three-line world list layout: world name / folder ID / last played are separate rows now, so a long name can no longer squeeze out the timestamp; the folder ID elides in the middle so the trailing = stays visible.
• Edge-swipe sidebar: swipe right within 18dp of the left edge to open; when open, swipe left anywhere to close. The scrim is fully transparent but still handles tap-to-close.
• Dark mode properly supported: two palettes (light / dark) were added and all 76 hard-coded colours in layouts and code now use theme colours; system dialogs (settings / backups / restore / root-node actions, etc.) follow along instead of staying white and unreadable.
• Permission check moved into Settings: the home header is now just "Clear cache / Switch path"; the permission check lives in Settings and runs a real test on tap, with a clear verdict.
• Seed copies on a single tap: no more long-press-and-select, and the emoji is no longer copied along with the number.
• Free-crop now honours the row/column count: previously choosing 5×5 and then switching to "Free crop" produced only 1 map; it now splits into the full 25.
• Square lock adjusts automatically: turning on "Lock ratio (square)" immediately snaps the crop box to the largest square, instead of waiting for you to drag it.

Fixed

• Saves written under root were unreadable by the game (most serious): files written as root are owned by root:root, while Minecraft runs as its own uid with rw------- permissions — so the files were there and the size looked fine, yet the game reported "Unable to connect to world" and the list showed an absurd 4167549952. Ownership is now handed back to the owning app before the write completes.
• Ownership repair looped on itself: the old logic preferred the ownership of the current db directory, so once it had been corrupted to root it stayed root and every save corrupted it again. The authoritative source is now the app's own directory.
• su command was split by the outer shell: when the command contained &&, only the first part ran as root while the rest ran as the ordinary app uid, so cp failed with Permission denied — it looked like "root can't write". The whole command is now passed as a single argument.
• Deleting an "app internal" world failed under root: /data/... is only visible to root, so the native existence check always returned false and the app claimed the world folder was missing.
• Automatic repair for already-broken saves: ownership is checked when a world is opened, so save files corrupted by earlier builds can be rescued without re-saving.
• Android 16 / HyperOS only said "cannot write": it now probes real writability and gives an actionable fix (HyperOS requires enabling "USB debugging (Security settings)" separately).
• Three sidebar interaction bugs: swiping stopped working after closing, the scrim was unclickable (taps fell through to the main screen), and there was no right-to-left close gesture.
• First swipe only showed the scrim / wrong width: the width read as 0 right after the view became visible, so positions were computed incorrectly.

• Recycle bin: deleting a world moves it there first, so nothing is unrecoverable
• Export .mcworld: pack a whole world into a file Minecraft can import directly
• Draft box: unsaved edits are kept in a draft box instead of interrupting with a pop-up
• Clipboard rework: copies also go to the system clipboard, in JSON / SNBT / plain text
• Export to file: to the Download folder, or to any folder you pick via SAF
• Full SAF support: read / write / delete all go through DocumentFile, and saving is no longer "falsely reported as successful"
• Unified world picker / draft box / backup lists, with a bottom tab bar and long-press menus
• Fixed: player data lost after adding a List — the root cause was deleting LevelDB index files
• Fixed: large worlds misdetected as LOCK and refusing to open
• Fixed: the tree view is now fully usable (add / edit / delete / search / save)
• Fixed: out-of-memory when generating map art
• Fixed: two inconsistent backup directory definitions ("clear backups" cleared an empty folder while reporting success)
• Fixed: opening Settings popped up the "custom" input box, and the panel could not scroll
• Fixed: crash when entering a custom draft interval / thread count
• Fixed: the session-restore dialog showed the wrong target; a discarded session no longer comes back
• Fixed: the tab bar would not stick to the bottom
• Fixed: issue #6 — saving to a custom path no longer falsely claims "Shizuku is required"
• Multi-threading settings actually take effect (file copy + map art, with tunable concurrency)
• Complete internationalization (EN / ZH string keys match exactly)
• Code reorganised by domain (nbt/ db/ editor/ world/ mapart/ util/)
• Renamed to Nibnya / 樱喵NBT, new icon, and the data folder NbtEditor_Data/ → Nibnya/

• Low memory on large worlds (the app can be killed by the system)
• Auto-update
• UI polish
• Backup policy (stop backing up on every save; time-based / opt-in / manual)
• Map plane view and editing (view / modify / move chunks)
• Multiple worlds open at once (the same world must not be opened twice)
• Blocktopograph-style theme
• Preset templates (player / village / map)
• One-click tools (32767 equipment, command-line items, …)
• A third page with handy Bedrock utilities
• Upgrading old worlds across major versions
• Multi-user support
• KMP cross-platform (Windows / Linux desktop)
