Linux doesn’t lack notes-taking applications at all, and Papyrus comes as a new addition to the large number of such programs.
Papyrus is a new, free, GPL3-licensed notes-taking application which tries to put emphasis on simplicity, with a clean, minimal interface, support for tabs, labels, and a few options to customize it. The first version, 1.0.0, is based on Qt 5 and was released earlier today.
