Settings can generally be transferred between flatpak and base system apps, but always make a backup before overwriting any config files.

Base system apps configs are in ~/.config usually and flatpak in ~/.var/app/appname (org.kde.okular in this case).

Yes but I never find the correct one. .okularrc and .okularpartrc have no effect.

Its not a huge problem though, setup it rather fast.

But in general having for example an RSS feed with important changelogs like this would be great.

We removed Okular, Kcalc and Gwenview from the base image now that they are available as Flatpaks from the Fedora Flatpak remote (and are also available from Flathub).

I'll have a blog ready soon that mention that, otherwise this was mentioned in the Fedora Release party talk:
- https://fedoraproject.org/wiki/Fedora_Linux_39_Release_Party_Schedule
- https://siosm.fedorapeople.org/2023%20Fedora%2039%20Release%20Party%20-%20What's%20new%20and%20what's%20next%20in%20Fedora%20Atomic%20Desktops.pdf

thanks for your answer! I agree its good to have it removed, I was just a bit confused.

What would be a good way to actually show changes like these to the users? Is there any adapted solution for changelogs in KDE, or simply a Kdialog on every release, showing one time with a button to delete it?

In the interim a small package could be devised that shows a popup notification for changes that the user should be aware of. If ostree version = x.y.z;then notify-send "Changes in Kinoite:\nOkular Removed - Add as flatpak if you need it";fi etc.

Ideally this should be part of https://pagure.io/fedora-kde/SIG/issue/295 (plasma welcome) but we didn't get to it yet.

@boredsquirrel If you're interested, you could take a look at https://invent.kde.org/plasma/plasma-welcome#extending-welcome-center-with-custom-pages and create a page for installing the Flatpaks in Plasma Welcome for Fedora.

Thanks, I will try to find the time
