tomscharbach I've found it best to use native KDE Plasma apps
To avoid GNOME apps never really seemed important to me, because although they brought with them additional dependencies -- and I understood that they would -- it didn't bother me much. I've never been so short on disk space that I needed to worry about it, and Linux apps are Linux apps regardless of DE, after all.
A recent revelation got me more interested in where the software was based. On a system with the Plasma DE, I'd always imported gnome-mahjongg, because I'd come from Budgie, and it was more familiar to me (tile designs, etc.) than kmahjongg. You've convinced me to give kmahjongg a chance, and I've found that it's indeed "first rate." Removing gnome-mahjongg only eliminated a single package. probably because I have other GNOME apps installed.
There are many times the number of different board maps available than in the GNOME version, and the default tiles are more complete. An option you can select will cause any matching tiles to blink when you first click any one of them. That's like right-clicking a tile in the GNOME version, but saves a click or two.
There is no reshuffle option when there are no more matches available, but in my case, it's rare that a reshuffle will allow me to win. And continuously clicking to reshuffle until I do win isn't any fun. So I don't miss that feature anyway.
In the future, I'm not going to install any GNOME apps without first looking to see whether a KDE version exists.
