On the browser extension make it so that you can do a VPN for only certain sites. For example, I have a domain that is blocked by my ISP even though 1) I own it 2) It is safe (it is blocked because it is one of those free domains - .qzz.io) and I would like it so that whenever I go onto that domain then Proton VPN works on that domain only not all of my tabs since some domains need localisation (eg. my server that only works in the UK).
