New asset: It's another UI Toolkit extension. This time Text Animation for any Text Element (yes, even your existing UI). I needed this for one of my projects which had some already existing UI with lot's of labels.

Links as affiliate links which means I do earn a commission if you purchase the asset. If you don't like that then I understand and here is the regular link:
