- open a file for editing, realize you needed admin rights, npp allows you to relaunch with escalation and keeping the change in memory
- find all gives you a list of items, a count of them, and quick preview of each
- supports the editorconfig format, so inherits rules you've designed for your other IDEs
- colors
- allows tail -f (the eye icon)
- can be extended with plugins (unlike notepad) although the out of the box works well enough for most (unlike vsc)
- less bloated than electron apps, when comparing with any vscode setup you would use for larger developments
- tracks which open files have had a change, lets you choose if you want to reload the file (update contents displayed without reopening the app) or not (helps you save what you're seeing before verifying what might have replaced it)
- lets you see and change encoding very easily
There's more, but I just picked a few things I find useful every day when I need to deal with many windows machines at a midsized company.
