I think of this all the time when I am 'teaking' my repertoire by looking at engine analysis: I sure wish (like in Chessbase) there was an analysis board in with the Engine Output so I could easily step thru the main line it is suggesting! Some days I can't do it all in my head...Boy would that be nice...and probably easy to incorporate.

When two lines are approximately equal, being able to step thru each to see which seems more to your individual taste...that would indeed be nice. Right now I have to manually put both lines in the program, step thru...then go back and remove the line I like least.
