  • Sheet rename now shows a validation warning for empty or invalid names instead of silently truncating characters

  • IME support: fixed input for Korean and other languages that use IME
  • Resolved a conflict where the uploader's drop zone blocked native text drag-and-drop (uploader now only reacts to images/files)
  • Images dragged from external web sources are no longer misinterpreted as file uploads (no empty-file errors in the console)

  • Markdown: <hr> element appeared instead of text in some cases
