Take temporary notes on your desktop, with this floating-note app. Notes are stored locally in a SQLite database.

This app is very simple, but demonstrates creation of decoration-less windows in PyQt. Removing the window decorations removes the means to drag windows around, so we must re-implement this behaviour ourselves.

If you want to learn more about build GUI applications with Python, take a look at my PyQt5 tutorials which covers everything you need to know to start building your own applications with PyQt5.
