Pretty simple suggestion, ability to select events inside a pattern and mute them. On the software it could be done with the mouse select and right click to show the mute button. In the hardware inside Step Mode or Events Mode it should be done by pressing Shift+Mute. The current way of achieving this is to duplicate the pattern and delete the events altho that works it doesn't leave as much space for experimenting until you find something interesting and kinda a forces you to commit to something that if you later on want to edit you will have to duplicate the pattern again and redo it all... Very counter productive. Here is a simple illustration.
