welcome to the By The Way, You Can Drag And Drop Things Into The Library Update!

first off, here's something you might not know: you can drag and drop things into the library!

• the docs now say you can drag and drop things into the library
• the text shown when a library is empty now indicates you can drag and drop images
• the add from search button in the library now shows a tooltip with an explanation (it also says you can drag and drop images)
• bug fixes
  • (1.20.1) fixed crash on launch (GH-58)
  • fixed capes randomly disappearing sometimes
  • fixed an issue that turned some player head items into steve sometimes (CB-12)
  • initial focus is now set properly on screens (this fixes an issue where having controlify installed would make typing in the library search miserable)
