I used to carry extra long VGA and USB cables so that I could position my laptop on a rostrum and to one side of a presentation. No longer so! Thank you Impress Remote. I recommend just using a hand held lasar pointer and don't give up on Bluetooth connection problems - it does work! My own problems with Bluetooth are due to a poor laptop and not this App. For large auditoriums or where the Bluetooth range is poor  definitely set up a WiFi connection. Now my laptop can be wired and left close to the data projector  and I just stand nearby  tablet in hand. Much better for audience attention as I can move about. Highly recommended. Improvements? Better resolution for the notes on handheld devices would be nice  but not essential. For some reason hidden slides in a presentation are shown by this App  the workaround is easy - save and use an abridged presentation.
