Time you spend fiddling with tools trying to replicate a tiny portion of what an IDE offers can be spent actually doing mental exercises to keep your brain healthy.

It's called working smart, not working hard.

I would absolutely fire someone who refused to use the mechanized tree harvester I provided and insisted on felling trees with an axe, and that's about where I stand with respect to insisting on using PDP-10 era text editors over an IDE.
