Bugs:

• When an navigation key is pressed, pause playback. #84
• Edit funscript without media #51
• Option to deselect when dragging with middle click. #66
• Customizable script suffix in the “add…” shortcuts. Pic
• Threshold to highlight slow strokes. So people don’t have to do this
• Gradually accelerating navigation with keys. So people don’t have to do this
• Vertical selection box. Something like this .
• Better handling of project window (prevent opening two instances of the same project, nesting multiple projects in the same window as tabs etc, allowing copying between projects etc.)
• Rearrange-able UI for plugins.
