Ability to only show an email icon in the system tray if there are unread messages.

Ability to open a specified URL instead of an email client when clicking a message, inbox, compose etc. This is for people using webmail (that is not Gmail, Yahoo etc).

It would be good if you could set digsby as a default email client. That way any email link found on the internet (mailto:info@etc) would automatically fall into digsby. At current you can't set it as a default email client.

Digsby already has an email notification sound but how about adding the option to customize this sound for different accounts? For example: I have 2 different POP3 accounts. Account "A" is my business account. Account "B" is my personal account. I want sound "A" to play when account "A" receives a message. I want sound "B" to play when account "B" receives a message.

Instead of multiple icons that clutter up the system tray, how about one single yet intuitive icon that is shared for all pop3 accounts. A "mouse-over" pop up could tell you the status of each of your accounts.

TLS support for emails

Right now, with POP email, when you delete an email in the digsby list, it actually deletes the mail from the server also. It would be nice if there is an option to leave mail on server, and let the actual client (ie. Outlook) do the deletion.

Add another link to the pop-out for emails, allowing the pop-out to expand so you can read the entire email, without opening up a new browser window.

Support for adding one or more MS Exchange email accounts to Digsby.

Support for Sametime IM protocol, and possibly to send emails via Lotus Notes.
