I've got good news and bad news in regards to GIMP Paint Studio that you may have heard of or noticed:
Good news: You should be able to upload the package to DeviantART now as they seem to have increased the zip file size limit dramatically to 200mb.
Bad news: GIMP 2.10 seems to read and write tool presets slightly differently in places (At least for the Windows version) and thus broke many of them.
Not' sure if this part is good news or bad news: I was able to recreate the tool presets that came with GIMP but it took some time just for those. I had to bounce back and forth between the old preset files to get the values/names of things and GIMP to make a new one for every preset that was broke for maximum accuracy. So while that means it's possible to remake them if need be, it would take a lot of time. Hence why I'm not sure if this is good news or bad news.
Talking about presets I pmed them in twitter giving feedback and reporting one issue. Not answered
I have not time neither interest in spending so much time when Krita is available for painting. I created GPS and i leave it open. Nobody contacted me, so if you want to spend your time fixing it, you can do it freely.
About bad news or good news... i think this is only a new that could happen in time.
