This looks really interesting, source-navigator has not been actively developed for years, source-insighter is windows-only, eclipse etc is just too heavy for code navigator.
however the 0.1 release is done on 2013.5.6 and that is it, not much development was done since then. Also the 'apt-get' list for compiling simply failed (could not find those packages) on debian 8.
while I really like a light-weight source code navigator,this one needs lots of work it seems.
