Code review comment for lp:~tpeeters/ubuntu-ui-toolkit/60-scectionScrolling

(Shift)Tab doesn't consistently switch between sections or from/ to sections - which is hard to tell in the first place as there's no focus ring - this branch was going to include that, which I asked to clarify before, but it doesn't.

Also, question, should the scroll arrows reveal instantly with no animation? It seems odd to me, but it probably is intentional, so just double-checking. UX is perfectly usable from my testing.
