As you can see from the screenshot same note opened in an external editor (Sublime for this context) allows me to scroll way past the last line (almost infinite if not defined in config) without restraining depending on the lines i have written.
Ok I see. I think we configured it like this so that there can be a gap at the bottom, but having a full screen as a gap didn't see necessary. Maybe there's some technical limitations too. I'm not sure we'll change this, unless someone's interested in looking into it, for example by increasing that bottom gap and check if the editor still works properly.
