...Krita Studio? Save for autoupdates managed by steam of course. I'm talking about differences in actual app. And if so, what are they?

Gemini has the Sketch UI and Desktop UI in one.

Studio is for studios and you get proffesional support+builds on centOS.

Krita only has desktop UI.

And sketch ui is for... what exactly? Just want to decide whether I need it or not.

I didn't want to start another topic...
I wonder why different versions have such a drastic change in setup file size: http://files.kde.org/krita/windows/
For example, the jump from krita_x64_2.8.79.14.msi to krita_x64_2.8.79.15.msi is 15MB. Later krita_x64_2.8.90.1.msi to krita_x64_2.8.90.2.msi shrunk on 20MB, went back to 160MB and shrunk again to 140MB. Is it some testing branch (e.g. animation?) that gets included or swiped out?
I am just curiosous =)

The difference in size can have a couple of reasons

* I might forget to strip the package of extra dll's and stuff, and sometimes I don't forget, which causes the fluctuation.
* the big increase was when I added the translations to the package

Ok, thanks =) So there's no correlation between the size and potential functionality.
