I think it boils down to ....... if you have buttons for it you dont have to need shortcuts......
But then buttons can clutter your workspace so you have to be carefull with to many of these.....
But couldnt that be done with an extra panel that you can fire up with only the plugins because
you wont be using them all the time and maybe 2-3 that you can choose from that you can integrate into your ususal panels..
Just a thought
