'Find Usages' feature to identify if a script routine is inside the block of if/else or while

Agree, i manage big projects so by time i've routines becoming unused.

But the function is already existing with the Find dialog. Perhaps just to improve the Find dialog by adding a checkbox "Method usage" which will do a clever usage finding (does the function is called in the executed code so evaluation of the usage according to the Test item checked to be played in Project Test Item management tab).
