Hi there.
First of all this app is really great, so thank you! Is there any way to select all trees that are on the map, or select many trees at once? Would be nice if we could do this by drawing a rectangle on the screen like in strategy games or windows explorer for example. Could we also have a "save as" button and a "load" button to go back to previous Versions, in case we end up not liking the changes we made?
