-The modulation window is not supposed to close when selecting another tab (just tested it on my side)
Yes my bad. It's only if you click a tab that's already open the modulation window close. Or if you somehow doubleclick.
I use the latest version yes.
-The function scope do react like you describe, when clicking on the Func3 scope it opens the Func3 window (same, just tested and it works)
Please look at the attached animated Gifs. You can't click at the left in a open modulation window/ strip to go to that that function, or to anything at all like Crafturate suggest was possible for all. And if you click the Function tab, then it open on the last selected Function, and that does'nt have to be the one you wan't. So this will mean 2 clicks no matter what you do.
Well there is something wrong with the file upload. I have 2 animated gifs. Each a little more than 1 MB, but it's said it's to large, even though it should'nt be so, as there should be room for 4 MB/ 4096 KB. That's quite annoying.
I attach an image of what i call a open modulation window/ strip for a modulator instead. When you click on the Function TAB, then you can't be sure it open on that same function, and you can't click at the shown display at the left like Crafturate suggest was possible for all modualtors.
