SUMMARY: If I had more time, I would strongly consider putting back on my dev hat and try programming a decent mobile experience for the Android vs. of Krita. BROKEN IMPORT AND EXPORT: I used v6 as my primary painting app. In v7, I tried to back up my projects and found the import and export utilities virtually unusable. The projects that I exported in Painter's native format were all 22 bytes (tiny, empty files). The .psd files that I created with v7 could be imported into Krita; they looked terrible when imported back into v7 of Painter. CHANGES TO UX: The UI looks similar to v6 but requires more manual gestures. You need to use 2 fingers to move around the brush palette and 4 fingers to hide the menus. In my opinion, simpler is better in mobile painting apps. Menu interactions should be concentrated on the stylus and not require me to change how I am holding my tablet or my drawing tool. LICENSE MIGRATION ISSUES: If you are trying to migrate a premium license, make sure that you only have one account associated with your device and Google Play Store. The migration fails otherwise.
