How do you completely disable the light bulb in Visual Studio 2015? It reminds me of Clippy.
I just found this extension:

The extension removes the huge left gap between the window start and the code, wiping out the light bulb. It's clear new VS are designed for 16:9 monitors and not for the good ones a.k.a. 5:4 ;)
The bad point is that removes EVERYTHING on that left gap, and this includes code folding. Good point is that the fold keybinding (Ctrl+M,Ctrl+M in my VS) still works.
If you hate the light bulb as much as I do it pays off at least until VS2022, where microsoft will decide to add an option to remove it and reintroduce Class Wizard for the fourth time.
EDIT: I found that https://marketplace.visualstudio.com/items?itemName=vs-publisher-403103.HideLightbulbMargin behaves better. It only disables light bulb but keeps the code folding.
