as an affinity product an affinity animator software would be welcome. a competitor to adobe after effects .
My suggestion is to bring aboard companies to co create the app (together they will make a superior product than standalone ).
The following are examples of companies with animation softwares at reasonable prices with features that if all put together would be a great app:
http://www.roughanimator.com/ https://www.keyshapeapp.com/ http://creature.kestrelmoon.com/ https://kiteapp.co/ https://creaceed.com/morphage/about http://www.coreanimator.com/#animate-anything-anywhere https://www.reallusion.com/crazytalk-animator/
I suggest that someone open up to making these companies come together with serif to make affinity animator :)
Have a nice day, today is father's day in Portugal, happy fathers day to all parents :)
