just one question – FlipaClip: Create 2D Animation Review

Hello! So i am a full premium member and everything has going very smoothly for weeks ( I did experience crashing but no progress was lost and it's rare and not an issue). But today I went to the color palettes and wanted to make a new one ( I think that's what it meant) and the app crashed. I went back and (no progress was lost) tried to do it again. It's not a major issue but I thought I should bring it to your attention;) oh and also I saw another review about this- the fill bucket won't always work and will spill across the whole frame no matter what I do but, again, not a major issue. Oh also the tool where you can select and move stuff doesn't work well by ah well no matter:) Finally, the ruler is very helpful but sometimes I have to take the app out of history and go in again because I can't add any more lines after using the ruler, but this is rare and again, not a major issue and no progress was lost. (QUICK SUGGESTION) Could there be accounts that you log into so you can do it across multiple devices? Like if your iPad breaks you can just do it on your computer or something -Thx P.S Thank you lots developer(s) for making this app as it is a very helpful app and is better than any other animation apps I have found;D also though I am experiencing issues they are small and my device is very old and I'm just glad it works as well as it does:) again thank you for the app and reading this review!
