Link to original bug (#764971)
Description
currently, groups have few value when exporting gimp animated brushes. Only the first layer of each group is saved, even if the said layer is hidden (eye off) Moreover, even hidden layers outside groups are considered before visible layers if they come before visible layers and you want to save only several of all layers for the brush
