I'm using emacs just for basic text file editing, no auto-completion, no flymake, etc.I find it quite dificult to navigate between files of a project and have no time to configure emacs to work as an IDE.
There are lots of plugins pointed out in the wiki and such, but there's a lack of step-by-step tutorials or packages that works out of the box. I always need to search the entire web for the lines I need to punch into .emacs file.
It's already hard to maintain brain's memory for other stuff, having to learn my way thru emacs was time consuming and yet if I would start a fresh-install of it, I probably would need to search the entire web again.
