We achieved a lot (incomplete list - many haven't added their achievements yet), but I want to particularly highlight the result of me teaming up with +Joren dc and +Tor Lillqvist. It is the new look of LibreOffice on OS X:
|Improved OS X look of LibreOffice|
Have a look at the toolbar - it is using CoreUI to render the gradient in a native way. It is based on similar work that has been done for Firefox - thank you, Markus Stange, for your observations & code, we have reused pieces under the MPL license.
It is visible that the work is not finished yet; we need to extend the gradient to cover even the title bar (or how is it called exactly?), but there is enough time for the LibreOffice 4.3 feature freeze in May - I am sure it will be perfect by then.
Other ImprovementsOther than that, I have extended the new Start Center to be able to show previews of other file formats than just ODF. As a sideeffect, it should improve the startup speed with many previews.
The last thing I've done was that I have converted the Template Manager to use dynamic widget layout. This led to removing many hacks there that made the Template Manager resizable even before - but using the .ui is much more elegant, and potentially may allow integration of the Template Manager directly into the Start Center.
Overall, the UX hackfest was awesome - I am really looking forward to the next one :-) Thank you, Mirek, for organizing it!
