[Sugar-devel] Scrollbar width

I'm with Eben completely with this.

SoaS needs a resonable way to scroll - both vertically and horizontally. 
External scrolling mice do a nice job of vertical scroll, as does the 
occasional laptop touchpad (the Intel Classmate is one).

Horizontal scrolling is another matter, with no obvious solution (for other 
than VM's?). With SoaS's narrow scrollbars, kids are left with a major 
impediment - as am I (a quite senior citizen with similar challenges).

I'd suggest, for starters, that SoaS scrollbars default to a width about 
double what they are currently.

I was a proponent for grab scrolling in the early days of Sugar at
OLPC. However, it seems clear now that, without customized hardware
(which was the assumption back then) this solution simply isn't viable
as an intuitive and discoverable way to navigate content. I think that
retaining the functionality via some other mapping or shortcut would
be nice (especially to offer the functionality as designed on the XO
hardware itself), but I don't see reason not to improve the usability
of Sugar on all platforms by increasing the scrollbars to a more
manageable width.

Of course, in addition to this we should make sure that wherever
possible the scrollbars are given every last pixel up to the edge of
the screen, so that they become, effectively infinite in width (or
height, when horizontal), thus making them difficult to miss.
