 ## TODO/Ideas
 
-- use github API?
-- options page to add loacation of headers for non-CMSSW repos?
-- or auto lookup - e.g. if #include "myEvent.h" link to same folder/myEvent.h, or #include "../myObj.h" link to ../myObj.h ?
-- options page? (keyboard shortcut, etc)
-- allow you to custom define where header files are?
 - if on a header page, add link to src file!
