Because "Global Inbox(Local Folders)" was defaulted for POP3 account definition ignoring many limitations on "Locla Folders"(bug though), many complaints due to limitations/bugs on "Local Folders" arose. And users are usually not familiar with special "Local Folders" concept even if they want "single mail box" feature. For first POP3 account definition, usual(non Global Inbox) account should be defaulted. For second or more accounts, if defaulted to "Global Inbox use", Global Inbox(deffering) to "default mail account" should be defaulted, which is usually the first POP3 account.
sorry, wontfix. We'll improve the local folders handling, instead of retreating...
David, see Bug 273778 and Bug 274330 Bug 275467, Bug 275467 especially, please. Do you still eager to continue explaining about current design and recovery procedure to every troubled people? :-) (Please note that I still agree on WONTFIX)
I think you're confusing design with bugs :-) there are bugs; I think it's most important to just fix them.
(In reply to comment #3) > I think you're confusing design with bugs :-) Yes I am, of course! (Theorem-1) Usual users never distinguish design with bug. (Theorem-2) Usual users usualy belive that any software action different form his prejudice is critical bug of the software. Therefore, there can not be difference between design and bug on the earth :-)
