It's unlikely (or wrongful to assume so anyway) that the InfoPop developers check out this forum for suggestions from users of this forum. Just like phpBB developers don't go around checking out people using their forums, why would the InfoPop people come here?
Experience tells me that Krejt, as a general rule, doesn't edit the source code himself for the reasons stated above - it doesn't make upgrading particularly easy. And due to the amount of traffic this board receives (200+ people every hour), risks and mistakes are not a good thing to have.
Whether future board upgrades (which will happen at some point) contain the features you want, depends on whether the board developers want that feature to be in the software release. Hence the suggestion to speak to them directly.
