Hey, yes the Gif export will got a really strong improvement in next release. Quicker and not freezing the app. I will let you know when it will be available.
I need to finish some improvements for 2D (like skew and resize the bones applying on the children) but ye I'm excited to add the 3d ability to add palette per material, adding internal line per material and/or following normal or depth. The result should be rly better.
