I'm working on a pretty big project, which have insane ammount of methods in each controller. Same with Views, one folder contains about 150 .cshtml files, what makes this hard to explore. I wanted to create separate folder for each part of window, but that changes my routing adress from ./Tavern/Shop to /Views/Tavern/Tavern/Shop. Tavern controller have 3000+ lines of code, and even with (Ctrl+F) its hard to find and edit some functionality.
Any ideas how can i improve this without changing many files in solution?
