thunderbird account folder

[unwashed potato!]

is there any add on that allows the email accounts for thunderbird to be sorted in folders, and then if possible be all shown in one list (rather then seperate for each account) and if you reply it replies from the address the email was sent to?

i ask as just got mum thunderbird and she really likes its cleanlyness and speed but would love it so she can sort work emails, personal emails, her partners emails etc into different folders.

thanks.

i looked and coldn't find any so thats why i ask here

thanks MarcLister, took a while but managed to get it sorted.

one last thing for now is everytime i send an email for the first time it asks for my password again, not much of an annoyance but enough of one that i'd prefer if it would go. any way to get rid of this?
