Dedicated Contacts tab - with custom groups, fields and quick links (to call, chat, send file, other apps integration..)
I think a contacts tab is (possibly with a compact view) to overview of the presence status and with customizable fields (add personal number, external contacts...)
Rolling over each contact the user should get the additional details and the possibility to click for on different functionalities (call, mail...)
Add a contacts tab as others have mentioned with functionality similar to Skype. I want to see my contacts and be able to chat, call, etc. from that screen. Currently, I have to decide to make a call or chat, then select contacts. The Chat interface is completely different from the call interface.
The Contacts option from the Calls Tab appears to already do what I am looking for, except it need to be added to the left menu bar for direct access.
This is absolutely needed for WFH model. I would like to be able to quickly check who is available from a Contact group when I need an answer fast. I need it to be on top and available all the time and not buried in a sub-folder. I used this feature in Sametime to know when I could contact someone abroad and now I need it for all my team.
