Is this the place to post ideas for the game? Here's a couple I've come up with:

1) It would be great to have the game work as a screensaver - rather than staying on the map screen or following certain islanders around it could flick between them after a while, giving more of an overview of what's happening.

2) In the Tech screen, pressing somewhere that isn't a button removes the current selection, e.g. if I select Harvesting and miss the info button ([censored] digitizer drift) I'll need to reselect it before I try again.

Anyone got any more?
