If I ever want to check/edit the style for a particular selector
sure here goto is better, but QuickEdit is designed to present all
selectors applying to an element, so you don't need to hunt all of them down, also don't need to think in selectors.
Sure, there are "go to defintion" plugins for C++ but QuickEdit has the advantage to present definition and usage at once: i find myself often working with two views, upper for actual coding and lowerto look up definition of function etc, QE streamlines this process
