All over what animated gif? But with which software?
In this project's case, it showcases a lot of features as they're actually used, rather than some bullets that say what it _should_ do. In general, I appreciate a gif like this for explaining because it boils down some essential features into one easily digestable clip. It's a preferable medium for me over a long YouTube video or text explaining how something works.
Like OP, I’m also a HUGE fan of cleanshot x for mac. Got our entire team on it, some were quite happy with the built-in screen grabbing tool on Mac, but pretty much all love Cleanshot.
