I put together a list of options you can set to remove all the Visual clutter from Visual Studio 2015:
I don't know if it's of any help, but you can use "Edit > Navigate to..." to switch between files. There is a hotkey to call it, on my keyboard layout (azerty fr-be) it's ctrl + ',' so it might be ctrl + 'm' (or the key at the right of 'n') on qwerty layouts.
- You'll need to type part of the name of the file you want to switch to;
- it lists other things than files;
- it's slow.
If your dead set on using Visual Studio then I highly recommend you get either ReSharper or Visual Assist, they do everything you asked for, and either everything that Casey does with emacs or just about. Only problem is they are not free although VA is a bit cheaper. I use VA at home and ReSharper at work.
