True. I also hate these reconnect dialogs. In general this is one of the most problematic issues with the N9 that they only leave you the choice between always on and do everything manually...very idiotic. So if Helium could simply reconnect to the (auto-dial) network it has been conneced to 5 min before (like the browser) I would be happy - maybe it already does and it just didn't work when i tried....
Sorry, that was a bit unclear. I meant the system-wide sharing dialog, If you press a photo or a file in your (installed file browser) you can often share those files by the methods N9 support. Bluetooth, Email, etc. Wouldn't it make sense to add UPnP there?
