I am looking for some way to autosave ad hoc notes on Linux. The main feature I am looking for is silently autosaving unsaved documents, where there is no need to explicitly save those notes when I close the program, and the program doesn't prompt me to save before closing.
On Windows, I use Notepad++ that has a feature where new, untitled documents are automatically saved (without prompting the user) and restored when the program is opened again.
On Linux, however, I have tried Notepadqq, which has the same feature, but it's too buggy for work use and doesn't have a lot of support.
Atom and Sublime may have this feature, but they are not lightweight and definitely not designed for quick notes. Notepadqq (and Notepad++) is much quicker, though the idea of the brief notes is not really part of it's intended use, either.
Wine is not an option, and if it were, I would still like to find a Linux solution.
EDIT/UPDATE: Offline only solutions, please. I am not interested in note keepers that require a remote login, or which generally focus on cloud-based repositories.
