Make GIF more smoothly animated

[1TSnakers]

you could add a few in-between frames to the generated gif animation (e.g. making it 30 fps instead of 10) and It would look much better!

I tried this at some point but it make the gif heavier, and it's already quite large :/

Could it be an option? Like adding a tag?
