===== PDF Catalogue (Working Title) =====
Software for organising, sorting, and viewing digital documents. Born out of frustration using [[calibre]]---wanting something more like [[foobar_2000]] and other music library organisers+players.

===== Ideas =====
  * [[PDF]]s (etc.) don't get moved to a a special folder, just leave them wherever you want / organise them however you want.
  * Be able to 'watch' the user's directory for changes, and update without prompting
  * [[metadata]] shares [[Calibre]]'s format (see the metadata.opf files, which are XML).
  * Super-customisable layout.
  * Fetch metadata online.
  * Custom filters: regex with a nice GUI interface if needed.
  * Use something zippy like [[MuPDF]] for rendering docs. That could be modular.
  * [[Python]] or [[FreePascal]], I guess.
  * Rely on existing system, so use 'outside' programs for things like pdf reading/rendering
  * config file for settings is fine.
    * library directory (i don't need multiple, but might be useful)
    * pdf viewer location, if want one not default (xdg-open)
    * [[exiftool]] location
    * location for 'collections'
  * 'panels'
    * file browser (or maybe not)
    * collections (like playlists, store as separate [[plaintext|plaintext]] lists of files)
    * keywords (tags)
    * author
    * subject

===== Research =====
(Just have this urge to do things in FreePascal, but Python seems way easier)
