There is a new browser-like navigation to the definition of variables
and to included files. You can Ctrl-click or Alt+Return on a variable
reference or include command (e.g. \sopranoMusic or \include
"somefile.ly") and Frescobaldi will jump to the included file, or to
the exact position of the definition of sopranoMusic (even if in an
included file).
Then you can Alt-Backspace to go back. There are also two new arrow
buttons in the toolbar for this. If you have multiple views and the
target document is visible in a different view, Frescobaldi will
nicely switch to the other view and back.

Enjoy,
and thanks to the early adopters of 2.0.14 that pointed out some bugs!
