My first impressions on cjots were that this could have a lot of uses beyond day-to-day to-do lists and mundane notes.
The home page says cjots is a text-only mimic of kjots, which apparently allows you to organize notes into pages, then into books. If you’ve used kjots and that sounds right, say so; I’m not a KDE fan, so a lot of the k*apps are foreign to me.
cjots, however, is very handy. It took me a little to get a handle on the arrangement, but once you understand the book-page-note relationship, you can find your way around cjots fairly easily.
One of the things I like about cjots (though this is probably by extension through kjots) is that it obviously has a broad scope for use. Instead of just being a to-do list manager or a text editor, cjots opens itself up to a lot of possibilities, by virtue of design.
