I'm not sure if this is a known issue or not, but using the Development server, anytime I do a search and click a search result, a stack is create and the selected page opens -- but the search results page does not get added to the stack. This means it's impossible to return to the search results, so you have to go back to the homescreen and rerun the search manually. This is a really critical bug that i've been seeing since at least Friday. Maybe it's just my dataset?
Logging out and back in fixes it for old stacks and the search result pages appear in the stacks, but if you create a new stack it still doesn't display the search result page.
