When I enter too much text or press "return" too often, the notes window resizes itself, it makes itself higher and higher. Eventually it will become higher than the screen and I can't reach the resize handle at the right bottom of the window anymore. When I delete text, the window does not make itself smaller again. So there is no way to reach the resize handle again and reduce the window back to a sensible size.

Wouldn't it be better to introduce a scrollbar instead, so that the window doesn't need to resize itself in the first place? Let the user decide how large he wants the window to be, so that it can show all text or not. And when he enters too much text, scroll it up.

Xpad and KNotes get this right, in my opinion.
