He has posted some interesting items; I'm working on framework for PP4 already and social networking interaction is at the top of my list, as are potential redesigns to the way we do templates (and a redesign of the interface as well to bring a cleaner look), and exploring a mobile skin, too.
I find it interesting they are looking at pulling back functionality, like members albums; I get the whole "simpler may be better", but we're had allot of pushback when we try to take functionality away even if its to try and improve the overall product. Even changing the way we show members photos (into the search area) was a big deal for some users. I can't even imagine the pushback we'd get it we eliminated members albums (or something like that).
The challenge for PhotoPost is not in supporting one product, but in support all products/integrations. We currently have three template sets - PhotoPost, vB3 and vB4. Changing one potentially means changing all and thats 3x the work (easily).
I'm not saying it wont be done - it will, but the complexity for us is much greater when we have to support more than one product. It seems clear to me that IP.Gallery will offer some of the functionality of PRO, but won't have nearly the versatility of it and, of course, will only work with IP.Board.
Please do not PM me for support or sales questions. Thank you for your understanding.
