I do not much care for the look either. http://www.reeftalk.com/gallery/
I did some work in PP8 in regards to vb4 as to trying to match up variables in the styles kind of like we do in vbGallery to make things a bit more friendly when try using multiple styles etc. Obviously also any plugins I created for vbulletin 4 are included in PP8. I also made sure with the plugins active that any relative profile links go the user users forum profile and all gallery profile content is displayed there. Lots of long time features users wanted.
The style changes I did because I too hate the default vb4 look and I recently bought a new style to test things out with. Trying to maintain consistency with so many styles can be a nightmare.
I one day when I have free time want to look into a Joomla PP integration it is all about finding the time. Who knows I found some time to do Xenforo and Wordpress. Not much time though after product support and development though to work on new integrations so things like that can take a long while.
