(Graphical) IDE's are great for development, but they're slow to start and heavy to run. Sometimes you just want to take a quick look at an xml or dockerfile and you don't want to spin up the whole IDE for that.
I've recently rediscovered notepad++ for that (on windows), what's your prefered easy-acces-tekst-editor?
Most of the configuration I've done in vim is to remove whatever someone else did. Like I log in as root on a server and someone put
set numberin/root/.vimrc. Like having the line number in the bottom right wasn't enough for you, you need to waste three columns to show numbers for every line on the screen, and now I can't copy and paste from vim without having to delete three columns from every line? NO.
