NBT Editor v1.10.0

Main Features:

/get lostitem history: View your cursor's history, in case you delete an item or it glitches out
/nbt export file: Export an item into a .nbt file
Drag .nbt files onto any inventory screen to get the item
Drag .nbt files into the editor screen to add the contents of the file
An API for modders looking to add their own features to the mod
A config option for unlimited client chest pages, which has some advantages and some drawbacks
Convert written books back into writable books by opening them and clicking the "Make Writable" button
When there is a new update, the NBT Editor icon will display "Update Available"
There are now three dots on the list entries' bar, signaling the existence of a previously not well known menu

Bug Fixes:

Fixed the key in the editor being unselected when clicking the value field or expand, in 1.19.3
Fixed /get hdb sometimes freezing the game indefinitely - it may still cause a brief freeze right after startup, but this is unlikely
Fixed clicking the same locked item twice causing it to be removed as if it wasn't locked
Fixed rapidly adding two items to the client chest and then switching pages causing the second item to not be saved, when the page contains lots of data
Fixed the /get help itemfactory command not showing information for the signature itemfactory
Fixed a crash in the editor, where changing the count to empty and then changing the id crashed the game
