Hey guys!

Assets Editor is an open-source editor for client 12+.

Requirements: Net Core 3.1 Features: Modifying objects. Copy flags between objects. Create new objects. Creating new sprites sheet, merging sprites, exporting and saving as lzma. Currently this editor doesn't check for common sense things, like if you didn't save the object and moved to new one it won't warn you about saving, or creating new object with wrong patterns.
