Hi Walter,

first of all thanks for your work!

I have been testing the device option on 850 XO-1.0 (it is just a matter 
of copying the files over from the 0.90 patch that just landed in master).

I find it quite hard to use the stylus mode as one really needs to 
scratch over the touchpad. Especially when one wants to revert the 
setting after using the stylus mode it is hard to reveal the frame, move 
to the icon and click it.

There have been discussions about which mode it should have after 
booting. Another case where it might hard to discover which mode one is 
using at that time is after suspend. You have to scratch as well in 
order to wake up the machine.


PS: style nitpick: I would capitalize the strings 'style' and 'finger' 
and align them left in the palette.

PSS: if others want to test on the XO-1.0 I can make some rpms quickly.
