Let’s split the work and make all KDE Apps available on Flathub!
Most of the work is already done upstream in the Flatpak KDE Applications repo but for nightly/master versions of the KDE Apps. Adding them to FlatHub is thus just a matter of updating the manifest to build against the latest stable release and pushing it for review to Flathub. See the PR I’ve just made for Ark for an example.
To track this work, I created this spreadsheet with the status of all KDE Apps on Flathub. If you find any missing app please add them! I added a priority column but this is purely a suggestion to package applications that would make the most impact by having them on Flathub.
(If Google Sheets is an issue for anybody willing to contribute, please contact me)
