When editing an interface, you should be able to control-click a function to go
directly to the implementation.  If there is more than one implementation, it
should bring up a drop down list with the available implementations.  Right now
it is very cumbersome because you have to right click on the function, select
find-usages, uncheck find usages, check find overiding methods, click next, then
click the search window to go to the implementation.  It takes 6 clicks to do
something that should be done in one.
