Yeah, that's not what I'm looking for. Windscribe has 200+ VPN locations. I'd have to manually import every single one. Sure, probably would take less time than it took writing this, but if they update a few configs (or everything at once for some reason), I'd have to go through the hassle of removing the existing configs and updating each one manually again.
If it had a batch importer or even just supported configs in /etc/wireguard (or a custom directory), that would also be great. But from what I understand, it's a frontend for NetworkManager, which uses a different configuration format for connections .nmconnection and is terribly documented.

I might have to rethink my stance on no browsers, because Dioxus looks very easy compared to slint. And it supports mobile, which might come in handy for other projects have I have in mind.
You do say dioxus has fairly rough edges. Could you elaborate further? I was considering trying it out.
