I’m gonna dip my toes into volunteering as a Flatpak/Flathub developer advocate—basically, providing a human contact at a real company that can help larger apps/companies get their apps in front of Linux (and thus Steam Deck!) users.
What are some of the biggest apps you think are missing from Flathub—or for apps already there, which are the ones you’d like to see verified?
@cassidy Probably boring, non professional environment answers but: Vivaldi web browser https://vivaldi.com/source/ is the first thing that comes to mind for me when it comes to stuff that I'd like to see have a flatpak but doesn't.
Also Sonic Robo Blast 2 Uncapped https://git.do.srb2.org/Fafabis/SRB2/-/tree/uncapped-build and a Dolphin Emulator Master branch (latest bleeding edge version for compatibility with certain features essentially, I'm aware dolphin emulator already has a flatpak but that's beta) https://github.com/dolphin-emu/dolphin
