Return to page after registering
Currently the page to return to is hard coded in register.php. I believe you can override this file.
What you are describing has been requested by other users.
1. Instead of a hard coded "Return to Home" link on the registration confirmation page, the "Return to" link destination can be selected in the dashboard.
2. Make the selectable "Return to" link an automatic redirect, so the registration confirmation page is "skipped".
I have this on my todo list.
