Hey there, this tool is rad, though there is one minor thing that I don't know if presently exists.

I have my eyes and mouth sprites set up as three-frame spritesets. This means I need a copy for idle of both, even though both instances are using the spriteset. I think it would be useful to be able to set a spriteset to be "reactive", where it'll stay on the first frame if not talking or blinking, and use the usual 1-2-3 animation if... well, animating.

A second useful feature would be being able to set an output source to react to, but this is largely me thinking about setting up a second PNGtuber for a Discord friend for our streams. (Where capture is all done on my end.) There may be more specific tools for something like that though.

Sorry for necro-ing, but I really wanted to say that I second this! I was just trying to do this very thing and found out myself that the blink doesn't actually use all the frames for the animation. It's a little sad since actually getting to animate a blink could really add a lot. This program is already awesome as it is and this is by no means a complaint, but if it would ever be possible to add this as a feature in the future, it would be greatly appreciated!
