Hey!
I know that. But its not always helpful, dont you think? Sometimes the window of one chest is covering the next object you want to open. Just using the right mouse button would be more convenient then moving away and/or closing manually.
Of course it is not completely off, the way it is handled, but it could be better in a more consistant way. I think

Edit: Do you always take everything there is out of chests? AND: Sometimes I like to be lazy and just use the mouse only.
But you guys are right, there are already plenty of options, just not the one most convenient, I think
apart from that - the other things I find more important
