Usually, when I’m selecting several items to group together there will be a larger element behind all those elements. In order to select all the elements I want without selecting the larger background element I have to first select the background element and lock it, then drag-select all the elements I want to group.
It would be cool if you could just hold a hotkey while click-dragging, and the first thing you click on will not be included in the selection. This would make it possible to click on a background element without selecting it with the group.
Anyone else think this would be useful to them?
