(Ok so continuing with this superb gmail UI) - drop Freetype alltogether - rewrite the plugin - create a binding using raffaillac sketch Now we need help. Who is willing to help us? Should we try to set up a bounty?

Hi all I'm and I guess many of you are fedup about the instability that the FreeType plugin produces. So we need help because clement and esteban are fully booked. We have three options: Does anybody Stef

Layout for placing widgets

Hi I was wondering if there is a layout that we can use to propose alternate placing layout for widgets in spec? Like attached to the left 10pixels rubber band box or fixed size box 10pixels attached to the right. Stef
