Martin,
I always wanted to look into the first issue, well, now I did, and
it's fixed. Look for a market update later today.
The second problem is a little harder. The default browser launches a
new activity on Android's activity stack for each page, so the stack
takes care of where to go back to.
Steel handles all this internally, so it might be harder to get back
to the calling application. I'll look into it more, but it won't be a
quick fix.
