It would be helpful if an inbuilt screen recorder could be added to Photoshop. What I mean by this is, if there could be a recorder which records each stroke of the brush as a different frame. When you are done with your illustration, an export button could give a popup asking for fps and other options. After this is done, the images would be put together to form a fluid animation. The recorder would work in a way that even after closing the app and opening it again, it would still be able to recorder starting from where you left off. I am only suggesting this because I used to use Krita which would have this feature and I found it very fun to use. Another potential advantage of this is that many artists like to post time-lapses like this on their social media.
