I saw this search bar, but sometime it disappears and I have to exit the app to get it back
I was more thinking of either the possibility to select/unselected calls to function and functions declarations
and/or having a regex in the search bar (that could be saved) to remove unwanted items
could also also thiese items grouped together (the one with the same name)

btw, it's a very good software, I use it to write few code lines in the public transport, then send to dropbox, and arriving at home the code is on the computer
