The drop down list should identify in some way those accounts that are in the default list. I monitor 12 accounts and can never remember which are set to default, it's a pain having to check each to see.

(A further improvement but not as easy would be to have acount groups so I can check mail for all in Group1 accounts, then all in Group 2 ets)

Yup, we've been asking for this for some time, and for a variety of reasons. See the thread here
