Running the make file will build and install the plugin using gimptools-2.0.
Otherwise you can copy the timeline file from the bin folder to your GIMP plugins folder.
Same goes here for the Makefile.
The bin/timeline.exe file is a prebuilt binary compiled for Windows 64 bit.
Frames are layer groups created by the plug-in.
However if you add a layer group yourself it won't be recognized by the plug-in.
Onion Skin will make the previous frame (layer group) slightly visible.
You can modify its opacity with the slider underneath.
Remove Keyframe will remove the currently selected keyframe.
Play opens up a new window that render the frame in order.
Create Sprite Sheet will create a new image where the layers will be positioned one after the other.
The number next to the button indicates how many image will be put in a row before a new row is made.
Copy last will copy the last frame in the timeline whenever you create a new frame.
