I am working on an update right now, it's just a little bit complicated. But I hope to finish it this month.
Regarding your wish: As Eggyslav explained those things are not possible. I'd love to do it, but there are technical limitations when you work on a website like this. And it's just a question of logic actually. If I change the pose of the body, all the clothes won't fit on it anymore. Because the clothes cannot "know" which pose the body has and change accordingly. This is something for an actual videogame, because it needs special coding. And another big problem is: For every pose of the body I'd need to draw alle the clothes in this shape as well to make them fit. This is not possible for one person, because it would mean months of work.
More than one character is not possible as well, because of the size of the canvas (it's too small) and the coding. Changing the size of the canvas would mean to change thousands of files. And then There should be an easy way to switch between the characters. This involves more complicated coding than possible right now.
I know those are no good news, but I hope I was able to explain the reasons. There will be many more updates in the future, but unfortunately those ideas are not realistic without a big budget (and I work for free so I cannot hire anybody
