Yes, in general the confirmation for transferring All (no search filters applied) is a very good thing, I do not want to see all my bag content go into the bank, because I misclicked a button.

However:

This is not necessary for transferring to SendMail.

Why?

There is a max of 12 slots, and the stuff is not sent before you click Send. And you can undo by simply closing the mailbox. So: No danger at all.

I have disabled the static popup in my copy, because I'll have to transfer lots (hundreds) of items via mail to another toon, because I have to close my AH account and open another one, for technical reasons.

But I also had the issue some time ago when I temporarily disabled one AH account and transferred all item to the AH toon on the other account. So, yeah, this may happen more than once.

Thanks for considering,
and thanks a lot for your incredibly great work that this addon is (Syndicator included ;)
