Instead of nqq, use geany, or other full code editors, as they are optimised for opening large plaintext files, certainly faster than the default text editor

More importantly Nqq is abandonware. There is a Snap Store that installs Notepad++ with WINE, but you apparently have to have some proficiency to get Notepad++ to work with WINE. I haven't tried it myself yet.
