[embryo]

• Updated to v2.3.0.0
  Added:
  • New User Guide. Can be accessed from the User Guide tab in the About dialog
    or online at GitHub.
  • System tab in the About dialog, with some basic system information.
  • Drag and drop support for changing the current database on the fly.
  • Experimental (and slightly hidden) support for splitting highlight chapters
    if exported to markdown.
  Changed:
  • Hitting the `Delete` keyboard key while in Books View, will just remove the
    selected book entries from the layout without deleting anything from the
    storage.
  Fixed:
  • Drag and drop of metadata files/folders was disabled.
  • Sorting highlights in Highlights View by Chapter name could lock the app.
  • Creating a new database file was not possible.
