through Edits - Hard edits

With scene detection and simplify sequence come the need of the option to make a through edit a "real" Hard edit possibility.  This for color purpose or exchange to other soft.

This for simplify sequence, because somethimes you used a through edit for let us sad put in a fade in same image from color to B&W, but simplify sequence remove the edit and the effect B&W . 

IS this an idea?
