.txt is good but .rtf is better
I love NP++ but sometimes I need formatting.
I use it to make notes about tickets I work. It would be great if it were like Word Pad so formatting could be used. I realize doing this would deactivate some features FOR THAT TAB but it would be worth it for me.
depending what formatting means for you it could be done by defining a user defined language.
