Thanks for the suggestion. After getting some weird behavior with Appimage Launcher and reading this reddit thread, I decided to install pamac-flatpak from the AUR, but plan on leaving AUR dissabled on the app. So far so good. I think it’s a keeper.
I like the integration with Timeshift and the into packed interface with ability to click on details. On the downside, the themes are limited and it’s kind of hard to use for browsing apps that you might want to install.
Lawnchair and Neo Launcher are close seconds but, unfortunately, there is no one for one alternative. Just use a firewall to block Nova’s internet access.
I don’t recommend downloading from unofficial distrobution channels without verifying a hash. That said, why doesn’t Exodus give Linux users a PPA? Mac and Windows both have auto updates for the Exodus wallet.
