So I know that software development takes a lot of time, work and money. At the moment I am just throwing away money every month to Adobe just to use After Effects which is broken/unusable in every other release but it's also the software I use in my stack 50% of the time. I love designer and never use illustrator anymore so if someone were to make a after effects alternative (fusion, vegas, nuke and natron do not have the tools to animate shapes and vectors well) I could ditch Adobe forever.
So please consider a after effects alternative. I would gladly put money into a kickstarter or something like that to support a company like Affinity in that kind of development.
We do plan on creating more software at the moment we are currently developing a desktop publishing application Affinity Publisher and Affinity Designer for iPad We don't have any immediate plans for an app similar to After Effects but that doesn't mean it can't happen.
