Make ripple Artboard tool in Illustrator
As someone who uses Illustrator to design much of my artwork for animation in After Effects there's one tool that I find I constantly need and instead just muddle through manually cutting, copying and pasting.
It'd be great to have a tool in AI that would insert a new Artboard between say frames 9 and 10, and then move all the artwork from frame 10 on up to the next artboards (frames 11, 12, 13, 14, etc.) I think of like a ripple edit tool. You can insert or delete a frame (artboard) and the artwork on all the artboards following your edit moves to fill the gap. It'd be great for working on sequential art where you constantly need to create a new frame in between existing artwork and then need to shuffle all the following artwork back or forward to keep it in sequence.

The blend tool kinda does this.
