[Feature] Add a filter for the apps selection section

[Mahantor]

Please add a filter feature to the select apps section so that only apps with special features are displayed For example, apps that have been updated and their backed up versions have a lower version Or apps that don't have backup I will put some filters that I think can be useful

also add these to the sort section Of course, I don't mean all these values ​​and I only put the photos as a suggestion

I was thinking of this as well. Especially miss the filters "installed", "not installed" and "both" which were present in the older version (1.1.x) before the UI revamp.
