We did it . I have worked for nearly one month on the Account Manager improvement in Instantbird, and the last patch was pushed a few hours ago!

Here is an overview of the improvements related to the Account Manager:

• Change default actions on the "Account manager dialog" (return now connect / disconnect instead of opening the property dialog).
• Focus the connect/disconnect button automatically (when selected an account).
• Wherever the focus is, make sure the up and down arrow change the selected account
• Add a context menu to the account manager.
• Make auto-reconnect cancelable/stoppable.
• Make account reordering possible (shift+up/down arrow, drag and drop, context menu).
• Disable buttons in account manager when offline (no connection).
• Update the alias in the account manager when it's changed from the properties dialog.
• Default action when deleting an account should be "Cancel".
• Account manager without account should not be just an empty white rectangle.
• Need to click twice on "OK" after editing an account without protocol.
• Disconnect button not disabled just after clicking on Connect.

The new tab system is nearly ready to come out, we still have the preference dialog, tray icon, little improvements on the buddy list and the conversation windows.
