Thanks for your reply, yeah I am using premium, I ran around the Tools -> Options "Main Window Theme" has various colours/fonts and under "Boxes" spacing, but I can't see anything related to the main scroll bar?
With the general themes, I can select different ones but there isn't any way I can see how to edit/tweak those?
I know 'modern' windows uses these same sized scroll bars that you guys use, but, the default is way to small.. like only a few pixels wide, this really needs to be larger.
Regarding the middle mouse button, yes I can scroll using the wheel, but would be good to be able to drag fast the entire screen with the middle mouse - this would be handy, like when you drag on an ipad or Adobe software just clicking and holding the middle mouse. (if you have 1000's of items you might want to just really fast get to the game knowing the alphabet/ordering etc).
Thanks
