Playback for Gimp 3 does not support layer groups, so this plugin is used to preview animations stored in a layer group.

I've added a few minor changes to the oryginal plugin:
- open layers in original size,
- specify the plugin's GUI start size [in line 42 you can change it (currently 700 x 800)],
- make the save as webp window open in the foreground,
- change the preview size increment [ - / + ] from 100% to 10%,
- change the menu location [ original location:Tools/Pixel Art/Animation Preview ] to: Filters ➤ Animation ➤ Playback Group Layer...
