Just my point of view:
1) Main windows - Accounts.
Right now it's showing all the accounts, that been set up.
Pressing the account name shows - "Connect - Edit - Remove" dialog.
It should be more easy to use the program if Long tap would show this dialog. Short tap should open contact list for this account.
This way there will be no need to press menu button for contacts.
2) Back hardware button behavior.
This issue related to Back hardware button (BHB) behavior, when you answering a message, through top bar notification.
Right now, after answering to a message, pressing BHB takes you back to the last screen you were on, before receiving a message (Not necessarily to IM+). May be it could be set up in Options, to give a user a choice - Go back to last used window, or - go back to the contact list for this account.
