Right now theme creator it's kinda slow, buggy and not friendly to use, theme creator does not offer much customization, otherwise you can do magic through photoshop, but they did not offer any template other then stock one. I would like to see templates with examples of which part is used for which asset, they made one huge file (over 120 mb) and put every system part that could be themed, if they separate every different part that would be really awesome, now you got to edit everything inside one file, it's not that hard to do that, but its really confusing, you need to visit their tutorial for every part, i don't really like that, it would took me ages to make one theme that i really like. It's good to see that Sony actually cares about users of their smartphones and i really really hope they will make more improvements while it's still in beta phase. Or they should make theme creator as standard application not completely java based with more options inside app or make more templates with less content, just to be easier to overview, edit and generally clearly.
