I know I mentioned something like this before in one of my billion posts, but this is an official request, if it's possible to do.
Basically, an editor to allow adding or altering of values before the main line is parsed. I'm sure that's confusing, so to clear it up, when double clicking on a destination title (list on right side) to bring up the format editor, have a little button on the right (near the options to choose a recently format, etc) to open up an 'pre-format editor', where the user can define (or change) values that are used in the format string.
So, for example, I could change {n} to something else if I wanted, or add a new value of {newN} or {n2} etc. Benefit here would be that if the same thing is done multiple times in the format string, or if the user wants to simplify how the format string looks, they can do it easily.
Of course, the values should be available to the command line as well, or perhaps include an option to specify a file to include for processing before the format string is used.
Could even make it so that little button toggles an 'expert' mode that opens up another editing window in the format editor, so someone could do real-time editing in either window.
Oh and before you go looking for a gun to shoot me with, try drinking a glass of wine instead... That will do a better job of relaxing the nerves I just rattled.
