My touchpad often runs out of physical surface when, say, I want to drag'n'drop a file. When my finger reaches the side of the touchpad before the mouse pointer gets to where it should be I have to cancel and start again with more momentum. In Windows when this happens and I don't lift my finger the mouse pointer continues to travel slowly in the same direction. In case I missed it, is there a setting in KDE Plasma 6 enabling that behaviour?

Another touchpad feature I am missing is the Back (as in browser Back) functionality I get in Windows when I tap the bottom left corner. Is that possible?

That's on a Lenovo Thinkpad X1 with Debian Trixie and KDE Plasma.

EDIT: I just discovered KDE Plasma 6 has a setting called 'Tap-and-drag lock'. If you lift your finger and quickly reposition you can continue dragging. That's the most intuitive method, and more elegant than Windows.
