Description Mateusz 2015-09-03 07:37:18 UTC
As per Fitt's law, screen edges are important target for cursor movement.


Scroll bar is very often used, don't have data for LibreOffice, but for Firefox it scores 95% in heatmap: https://heatmap.mozillalabs.com/

So when sidebar is enabled, it breaks this important workflow (move cursor to the right, can't catch scroll bar) and increases user frustration.

Maybe it should actually be on the left of the screen (if not by default, then as an option)?

Or maybe sidebar should be on the right, but scroll bar would be better placed at screen edge?

Many projects struggled with this aspect:

So as innovation in UI is great, it shouldn't mess up with this important law and scroll bar position.

You can dock the sidebar on the left if you want. 
I use the scrollbar very rarely in LibreOffice (and never in Firefox) because the mouse wheel (or the touchpad) is more usable. So having the sidebar on the right side is more important than the scrollbar, but the scrollbar must be  close to the area it controls. So for me the current disposition is the best and simple one.

thank you for your reply. I didn't know I can undock sidebar and move it to the left.

I understand that current situation suits your needs. Can we discuss what could be the best solution for the majority of users?
