Hypnotix providers edit & remove functions don't work

[Vasilis_K]

After upgrading from Mint 20 to 20.1, I tried Hypnotix which is included by default in 20.1. The app is great, but after adding some providers I found out that the "edit" and "remove" buttons next to them do not work. They simply do nothing. So, the only way to remove them is by going back to default and thus remove all of them (except the default one).

P.S. Adding a bookmarks-favorites feature would be really great!
