How many people use the SWF library to organize animations?
I think most haxe games generally avoid Adobe Animate due to subscription costs and the effort of getting data into a suitable format for tilemap. In the early days of haxe is was common to organise assets in a swf library but largely that time has gone. But if it works well for you then there is nothing wrong with this approach and ideal if you have Animate for quick prototyping visuals with code. Haxe games that animate with vector assets are probably rarer these days, it is better to animate with code and shaders for GPU processing speed.
