Kostya: I understand your .... em... confusion.
I shared some insight into that issue in the part of the message addressed to Paris Geek:
http://www.aqua-mail.com/forum/index.php?topic=4289.msg23459#msg23459On a more serious note, - I think it is just a shift of the "scale": (as indicated in that message linked above). In Unix and DOS (and I don't know about early MacOS), there was no "Recycle Bin". "rm" or "del" were final. That was the base line.
Various software vendors, including MS and Apple decided to make a "safety net" for people who do move hands faster than think. With the time, that became a new base line.
And now people want to "un-send" messages (Outlook has "recall" a message).
But yes, that's a human nature to make mistakes. (And I do make them as well.)
You can either adjust your work process to minimize the chances of mistakes, and deal with those rear cases when they happen, or you continue being reluctant, while relying on the crutches provided by software manufacturers, and call it your workflow. The second is a more "hands down" approach, hence the obvious choice.{*} And when that becomes the new base line, - there is an escalation/inflation of the safety net desires.
Having said all that, in this case, I simply advocated the logic that goes with the already-implemented feature.
