Inherited a massive code base today... All JS is still being accessed via global scope... what are modules & modular design even... SOLID and DRY are things that clearly never crossed the devs mind during inception of this beast... and to top it all off all there is a weird BEM / SCSS style going on that somehow manages to confuse the IDE... thus all style helper utilities in the IDE are useless...

Sticking with emacs as my favorite editor. Navigation within files is easy. Working on multiple files also. I don't have to leave my editor to use the shell and can manage my filesystem as well. And the most important feature for me is tramp. When working with distributed systems it is pretty nice to access the remote filesystems from your local machine.
