gitweb.cgi feature request: project list "last change" column to display last change of all heads.

 Hi,
 I am working with the cinelerra-CV group (cvs.cinelerra.org) and we are 
 starting to use git to develop new patches.  Someone has offered to 
 mirror our git branches to share amongst ourselves at 
 http://www.pipapo.org/gitweb.
 
 The annoying thing is that in our mirrored personal repositories, we 
 switch from head to head and push new features in different head, and 
 then wait for the other developers to review.  At the moment, the 
 getweb.cgi script only shows the "Last Change" for the current branch, 
 and not all branches, (i.e. it's currently showing "13 days ago" for 
 cinelerra-pmdumuid, whilst if you click the summary, you'll see I 
 actually extended one of the branches only "24 hours ago".
 
 2nd feature request it the ability to browse to the next / previous 
 commit when looking at a commitdiff...
