I realise you mentioned that because of some problem you (Jack ) were unable to change the code so that the Bluetooth connections dialog gets dismissed simply by pressing somewhere outside of the dialog, but I just noticed that the Quantiloop BT connections dialog does allow one to do this so it is clearly possible.
being able to dismiss modal dialogue like the SETTINGS window etc - by simply pressing somewhere outside is a standard iOS ( and often OSX ) behaviour - and it makes using such apps much less of a hassle. Specially when compared with having to locate that tiny X "done" button and press it.
If you can spend a bit of time to do that it would be really appreciated - because for Bluetooth users anything that reduces the hassles is a good thing.
And on the same note - second request: Having to specifically tell GTL ( or iPad ) to connect to a bluetooth device EVERY time one launches - is a drag.
Is there any way that GTL can automatically connect to a bluetooth device if it has previously been paired with a specific BT device ? Apple Macs do this with keyboards and mouse.
Even if it required a single prompt - asking "Would you like to connect to your [IK BlueBoard... etc] ? " would be so handy.
