Can't list more than 30~ configs at a time

[skittles9823]

Just an issue i'd imagine not many people would run into, but for those of us who use this as well as mullvad which can have about 175~ different wireguard servers using this applet is a bit limited in the fact it can only show about 30~ configs at a time and as far as i can tell, cant scroll.

It would be nice if scrolling capabilties were to be added for those of us with many different wireguard configs.

another suggestion would be to show folders in /etc/wireguard/ and be able to expand folders and select from there.

Realised i should be using the Mint applets repo for issues, will move this there.
