Software that is based on such a great idea of backlinks should not turn off users just because from the start they need to learn css and a lot of shortcuts just to do such a basic operation as font change or bolding some text.
Besides now font size in editor is different form font size in preview

It really needs to be addressed by developers not by users.
I don’t want to be rude but it is really note taking app, not “learn css” app.
