RFE: "Look in" in QFileDialog is fixed to "/styles"

Look at mscore/files.cpp line 1393 ...
No matter which file you are trying to open (Plugin, Template ...) the "Look in" will list "styles" .

It is not a big deal, just maybe confusing.

But this "Look in" is a great feature that could be leverage to allow the user to quickly access multiple path. Typically all the "/usr/share/mscore-.../{styles, templates, demos, plugins ...}" There should be a way to pass it as a parameter. That would be great.
