Hi,
In Flamingo, we have created the concept of Application Bar, that we have
implemented as a Panel:
http://jira.xwiki.org/browse/XWIKI-10254
I propose to put the Application Bar by default on the left column.
Since we do not have a configuration system at the skin level, it would be
present for both Colibri & Flamingo. I think it is not a problem because I
have managed to make it look good for both (except for the size of the
icons) :

WDYT?
Thanks,
Guillaume
