1. often it is really hard to get it running. Then all the tabs (feed, places, ...) remain white and it says "please wait" for any time span. First I thought it might be a problem with the FourSquare server, but it is not: other apps connect fine.
But if I put it into foreground and even if I click on "places" it does not reload the list of places, maybe, or it loads the list but clutters it with the places of my last position. Anyway, I do not see the new, nearer venues even if I scroll down the list.
I suggest Nelisquare should reload the list of places when the user clicks on that button/tab.
