I think open files list would work better if it had single click select to choose the source file rather than double click. It's driving me crazy to have to double click to view the file, I guess mainly because how it's implemented in Visual Studio (the right way). I tried to search if anyone had mentioned this, but no one, really? Also, Visual Studio doesn't even show tabs for files, because if you have them in the list it's not needed, because you can just select the file from the list. I'm using 20.03.
