It might be just me, I use Visual Studio to write C# (not my "first" language) plugins for an older (non C# core) tool. Sometimes I also use Visual Studio to manage SSIS ETL packages, but I need an older VS version because they are not always backwards compatible - this leaves me with three versions installed on my computer - 2015,2017 and 2019 - each for something else.

To be honest what I don't like is the neverending march of tiled frames for everything - the whole program is one frame, then i have one frame for the code, one frame for the solution explorer, two more frames for error list and output, another one for properties and so on. A lot of screen space is taken by just blank spaces or dividers.

Another thing that I didn't like was that the 'Comment selection' option is hidden in Edit -> Advanced -> Comment selection. You also have to use two keyboard shortcuts in succession to comment something (Ctrl+K, Ctrl+C) and the uncomment shortcut is different (Ctrl+K, Ctrl+U). All this while Ctrl + / does nothing and could do both at the same time.

I often need the whole VS solution and not just the code when I need to copy paste the project to a different folder or a different machine.

Have you tried moving the frames around a bit? I normally dump all the frames down the bottom particularly for debugging.

The double-keystroke thing is a bit odd yes, and the menu is hidden a bit far away for ease of navigation. Still, it could be worse - it could be a RIBBON!
