Here is a little update for your plugin, Export canvas into an animated gif.
First use action Set Delay between frames.
Then use action Start Recoring Animation to start a new animation.
Then use action Add Canvas As Frame (repeat as many times as you want).
To close the animation use action Export Animated GIF.
Now you can access the file for download or for saving with the expression canvas.encodedGif
