it is what ESS can do.

Not using it. Never used Vim either.

Yes, some modes integrate flymake and other modes use semantic parsing
of the code directly in emacs. The name of it is "semantic":
ESS doesn't implement any of it. There wasn't much demand.

Yes, there are plenty. You can use prebuilt tag tables (M-.). In ESS,
C-c C-e C-t builds a tag table for directory. Then use M-. to
navigate. You can use external library like imanu-anywhere
https://github.com/vitoshka/imenu-anywhere (available form MELPA) to
navigate between symbols in all open files of the same mode. Works for

Emacs comes and allows for theming. Plenty of themes are available.

There are packages specifically designed for refactoring.

yes, all this is available by default or by packages:
http://melpa.milkbox.net, but it is mode dependent and you should
figure it out yourself.
