My reason to click (actually double-click!) a synth is to open the synth's GUI (as the title of this thread says) and make some changes there. For me, once the midi arrangement is done, it's done. My reason to open the synth is almost never to work with the midi track (does anyone?), so the jumping is not helpful at all. On the contrary, most of the times I want to continue working on a different track I was working on. A good example is a drum synth - I'm mixing the individual tracks for the synth most of the time (and not arranging midi). I want to open the synth and stay on the track without scrolling up and down all the time. Just one example out of many.
I understand we have our own workflows, why I wish it could be possible to open synth without jumping to midi track. Perhaps shift+double-click or something like that.
