Alternative to Treepad, Comodo friendly?

Do you know a safe alternative for a basic free Treepad?

I used it for years, but Comodo is alerted by its requirements. So something that is Comodo friendly and generally known as not containing any built-in malware.

Treepad LT is a small note taking application, that allows create txt notes in tree-like folders/subfolders structure, in easily recoverable format.

Anything good, from your experience?
