It would! But don’t stop there. Navigation and focus issues for users who avoid mousing around via a DAW controller, and use of key commands IMO is greatly lacking.
The problem as I see it goes back to priorities and marketing. I use 2 LG 32-inch Ultra-Wides and a LG 28 inch ultra-wide (the 28 inch dedicated to editors and VST GUI’s.) But I think I’m a minority user. I think most Cubase users are on a single laptop. So the suggestion of clicking on the “e” would definitely help those with limited space or single monitors.
One way to avoid hidden effects which is definitely a work-around, but has distinct benefits, is the use of workspaces. Look at the tracks that have the most effect inserts. Pick one, and open all the effect inserts on that track. Arrange the effect GUI’s so they display the way you wish. On mine I arrange them from top to bottom. Save that as a Workspace. Assign that workspace to a Key Command. Next time you want to look at any effect on a particular channel, and look at it in an organized manner, focus the channel, click the key command and that workspace comes to front.
