Nice work. Something I've wanted before, but I'm a little confused by the UX.
I upload a gif, select a frame, modify it. But then I seem to only be able to add it to the end of the gif?
Changes are not made to the existing frame.
And I don't seem to be able to change the order of frames (ie: move the modified frame to it's original position).
I recently used this tool (https://ezgif.com/add-text), which got the job done. The most useful feature on it was the capability to set "x frame to x frame". ie: add text from frame 25 - end or 25 - 40.
The combination of your layers feature, plus frame x to x, would make this quite productive.
