First: I´m delighted and impressed with the frequency of beta-releases, A joy checking for updates every night :)
On Beta6 it was really nice to see the interface improvements. Border on the gutter, and a elegant wrap-line really, makes a difference.. So much so, that I instantly made replacements for the folding widgets. Based on my previously released mock-up; The arrow-directions are more visible, and the ellipsis got a minor tweak to work better on dark backgrounds. It still looks a bit messy when a document has many foldings, so I included a set of light arrows which I propose to use on level 2 and below.
Differencing background-color of the folding column from the rest of the gutter, would also be nice.. I believe :)
