[RFE] Add filter to the search: Licence, Update,

It would be nice to have more filters, but keep it simple:

  • Licence: Proprietary / Free
  • Last update: maximum Years since last update
  • Number of Downloads, ratings, Git(Hub|Lab) stars …
  • Size: maybe useless, not a good example …
  • Platform: Gnome / KDE / Electron JS / … (I know they are compatible, but some might prefer " native" apps or avoid Electron apps)

I am not saying that it should be all pushed upfront ! Some might be only accessible via keywords in the request like pdf platform:gnome LastUpdate:2 a help page would describe the operators.
