Hello,
Nice software, but for me the part which would be improvable is the "Mail accounts" dialog box.
Here some ideas :
1. Maybe two panels: name at left side and details/properties at right side (to avoid to open/close another box to reach the properties).
2. A button to duplicate an account (since sometime you have several mailboxes at same domain and it would be easier to just change the username).
3. I saw that when you edit the mail accounts and an automatic email check is triggered, it's a blocking task. So maybe the check could be outside main UI-related thread.
Well, no emergency, but just some suggestions as it comes in my mind.
Mail accounts improvements...
