It's not. A popup to take a modifier is generally a pretty seamless operation; certainly no more unwieldy than typing the dice roll in the first place. I'm not particularly in favor of too many additions to the macro system that are being suggested here and there - if conditions, complex sorting, etc. are not something I'm really interested in (not to suggest that the people who do want them are bad or wrong, just that I personally think a lot of it can be dispensed with). I have other solutions for complex games, as it is.
On the other hand, a few things would be nice to see. For instance, as suggested elsewhere, a way to say "best of two dice rolls" (for Savage Worlds). Or just a "min" and "max" option - best of N rolls, worst of N rolls. Similarly, a way to issue a simple popup prompt for a modifier to a roll (default it to 0, let "Enter" close the popup if it's not needed, of course) would be nice for the folks that want to use the macro button bar without having to code a macro for each possible modifier. Since it wouldn't have to be used, it seems like a win.
Of course, I am speaking from the POV of someone who would rather change VTTs than be forced to use a manually typed dice roll or macro alias. So I'm kinda out on the fringe.
