Notepad++ - This is the definitive notepad-related software you’ll ever need. Multiple tabs, keeps tracks of lines, lots of features and preferences. One of the most invaluable parts of it, is that you can close it or a update happens or maybe your PC will get knocked offline. You can come back to Notepad++, open it, and everything will be retained.
NP++ handles so many things well, but then struggles with others. Opening a 3gb text file? Fuck it no problem. Trying to do find on a file 1/10th the size? Nah. You’re waiting a minute for it to stop freezing.
