This is a feature that should be added immediately. Rider is crazy to navigate. I use the solution view to scope to my project. But because I am using Unity, Rider also sees all of my plugins and extension code. Even though I can't edit any of it.
Everyone knows that adding a feature to a feature request for a large company will mostly get it swept under the rug.
It would be incredibly helpful to just have a window on the left pane that displays only the methods of the class I have open. It should also be able to scope to parent/child classes, interfaces and other linked functions. I know of the structure window but its useless also adding in all the variables. It even positions the variables in the order they occur in the file. I get variables, function, variables, functions that I need. In this huge list. What a mess.
