Great application. Some glitches and improvements are needed.
1. Proxy/firewall support
2. Disconnections in email and IM accounts
3. Ability to change status on each IM service separately
4. Three levels of grouping for IM contacts can be useful (as an ex. first level for the service and the other two by status and by group)
5. I couldn't get pop3 to work. Need to do more testing
6. Ability to see the email/Facebook in the Digsby bar rather than another bar
