LiveNBT v0.4.0 — ease-of-use update

LiveNBT v0.4.0 — the ease-of-use release

The editing workflow from NBT Studio, adapted for live editing. Every change here is additive — the connect/edit/watch/inventory flows you already use behave exactly as before — and everything works against the running game (no files, no saving).

App-only update. The agent is unchanged from v0.3.0, so if you run a dedicated server you do not need to redeploy anything — just update the desktop app.

New

• Keyboard-first editing (select a row, keep the tree focused): Enter/Ctrl+E edit, F2 rename, Del delete (selection jumps to the next sibling so you can rapid-delete), Space/Ctrl+Space expand, Ctrl+Up jump to parent, Alt+Up/Alt+Down reorder list elements.
• SNBT clipboard — Ctrl+C copy as SNBT, Ctrl+Shift+C copy path, Ctrl+X cut, Ctrl+V paste. Compound keys copy as name:value, so tags round-trip cleanly with NBT Studio.
• Undo / Redo — Ctrl+Z / Ctrl+Shift+Z (or Ctrl+Y) for every edit you make: set, add, delete, paste, duplicate, rename, reorder. Live-editor semantics — undo restores the value as it was right before your edit.
• Duplicate (Ctrl+D) with automatic Name1, Name2… naming.
• Edit as SNBT (Ctrl+Shift+E) — a whole tag as multiline text (also how you edit long or multiline strings); type-checked so a set can't accidentally change a tag's type. Plus Add as SNBT and a Quick add submenu (typed tag, auto-named, no dialog).
• Deep find (Ctrl+Shift+F) — search every name and value in the loaded tree (regex optional), jump hit to hit, or list all results and click to jump. The old Ctrl+F top-level filter is unchanged.
• In-app Help — F1 or the ❔ Help button opens a full usage guide and shortcut reference.
• Quality of life — colored type chips, tooltips for long strings and arrays, Ctrl+mouse wheel tree zoom (remembered), byte/int/long array creation, watch entries get a ✕ to remove and double-click to jump, and context-menu items grey out where the game doesn't allow the operation.

Changed

• Adding or deleting a tag now refreshes just the affected branch — the tree no longer collapses after a structural edit; expansion, selection and scroll survive.

Downloads

• LiveNBT.App.exe — the standalone desktop app. Just run it; no install, no .NET needed. This is the update most people want.
• LiveNBT-Setup.exe — installer that also wires the -javaagent into your Minecraft launcher profiles (for the permanent, AV-safe path).
• livenbt-agent.jar — the server/dedicated-server agent, unchanged from v0.3.0 (included here for convenience; you don't need to re-download it if you already have v0.3.0 deployed).

The exes are unsigned, so SmartScreen may warn on first run (More info → Run anyway). Full docs in the README.
