(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?
Geany or (with a lot of reconfiguration) Kate.
Geany is built upon the same text edit control as Notepad++.
Same for me, I even use it on Mac OS X too (which somehow still doesn’t ship with a basic text editor).
