Add option to merge frames
Maybe I just haven’t found out how to do it yet but it seems like there’s no way to combine or merge frames together, yet I think that could be useful to fill some blanks parts of animation, instead of having to erase the blank frames then copy/pasting the part we want to extend.
You can merge a layer by pressing and holding on a layer in the menu and dragging it to another one. Hope this helped! (or maybe im too late and you already know how to do all that stuff)
