Merge Calls and Chat
PSTN Calls have a dedicated tab. Merging with "Chats" could be a good thing since they are both a conversation, just a different media. Currently Chats allows IM, Voice, Video, just add PSTN as an option to reach user, and include PSTN-only Users (Outlook contact, dial pad). Would make the GUI simplier.

Agree! - Would be great if Chat was simply "Conversations" - and threaded direct communications regardless of medium (i.e. IM, email & calls) - Voicemail and missed calls could be linked to the chat thread.
"Speed Dial" would simply be "Pinned Contacts"
Contacts would be moved as a dedicated app on the left rail.
