I use JPEXS Flash Decompiler to edit swf files. Sometimes I need to
add a lot of frames into a sprite so adding ShowFrame tags one by one is
long and inconvenient. So I wanted to ask if adding option, which allows
to add user-specified number of frames into a sprite, is possible in
further updates of decompiler. Thanks for your attention.
Also would be nice if we can insert frames anywhere, because right now frames can only be
added at the end of all existing frames.
We added this feature in nightly 2079.
You can right click a frame, then there is context menu with menuitems "add frame
before/after".
