Skype has 3 settings for the Sidebar: Compact, regular, Detailed. It would be great if you could add a compact sidebar as on skype since as you can see in the attachment I can fit 3 times more chats and contacts than on Teams side bar. for the same window size i can have more than 30 chats visible on the favorites list while on Teams i can see a list of 11.
