Hallo-yes,well you can get what you want,but there are steps involved and will not 'stay' as a tiny tab-- you have to keep manipulating that- the smallest i've found is a box 3/4 size of the scale finder,but it can be
transparent +floating
always on top.
I think you need to set some other options to have no frames and allow toolbar icons to scale below 1.
This little box can be set to 1 side or w/e-kinda neat. =)
*oops-edit* Btw-this is using the toolbar docker with just 2 tabs-it can be hotkeyed,rea_scaled and moved around screen with 2nd tab ok.
