Changelog
+ Total rewrite! The program looks and works completely different
+ So much faster! No more crashes trying to import or load maps, or lag scrolling down lists
+ More efficient home screen shows all Java and Bedrock worlds at once, one click to open
+ Maps in world load asynchronously, speeding up worlds with thousands of maps (no need to "load more" anymore!)
+ Importing and existing sections are visible at the same time
+ Checkbox to show/hide empty maps
+ Import map window now shows a navigable queue of pending images
+ New import options: rotate, flip, set background color, crop fill, multiple dithering options
+ Warning icons alert you when changing map IDs may overwrite other maps
+ You can press Ctrl-Z and Ctrl-Shift-Z to undo and redo all operations, including imports, transfers, ID changes, and deletions! (no more "are you sure" popups!)
+ Export a combined map grid image, with maps from either the import or existing side
+ Generate structure blocks! No more manually pulling maps from chests and putting them on the wall, just place the structure block and go!
+ Fixed some leveldb issues, it should crash less?
+ Probably some other improvements I can't think of now
