Add a filter option for easier Wireguard selection

[tsasam]

I have loaded all Wireguard profiles from my VPN into the app (several hundred entries). Now and then I have to change the server to access homepages and being able to filter/search in the whole list would help a lot. Currently I have to scroll through the whole list. Would that be possible? Thanks!

Actually an "apps white list" and/or "apps black list" option, both lists exportable and importable across wireguard configuration, would be extremely useful.
Indeed the "Add/Remove" + "Always-on" is very tedious, in the case one just wants to exclude/black list a few apps from wireguard, which is not easy to achieve.
