I am very, very good with Emacs. There are no other editing platforms that have its power and convenience. If I didn't have it, I would be forced to invent it. (I did in fact do a small Emacs implementation for a microcomputer, back in the 80s. It was fun).

My customizations? Nada. I rarely bother. My ".emacs" file is about 20 lines long, mostly turning stuff off that I don't care for.

If you whip up a tool that is /better/ at working with million-line-plus projects in C/C++, let me know. You seem to be on fire about it.

[I use Visual Studio for C#, and for its debugger. But the heavy lifting is still done in Emacs]
