Emptying containers should have a ~1-2 second timer that you can break if you misclicked

I'd prefer the "are you sure?" prompt that I see elsewhere, though those are added by Amber it seems.
Failing that, this is a good alternate suggestion. But then with this you have to actually realise you've done something wrong, rather than having it pointed out to you.
Besides, an additional click from a prompt when you expect it will likely take less time than the 2 second delay, and be more likely to save your stock when you're not expecting it.

Have since implemented a timer on emptying. I'm happy enough with that, and not a fan of "Are you sure?" prompts.
