Great program in general, it has been perfect for my recent projects apart from one huge time waster, why is Next Frame's shortcut Right Arrow Key & Previous Frame's Left Arrow Key? In a piece of animation software having a dedicated button for these two actions would be incredibly helpful (along with a larger jump back and forth). Personally I'd like fully customisable shortcut/Hotkey options, but at the very least make those two useable while I'm also navigating an editor, puppet etc.
