Chat window drawer tricks
If you happen to be one of the many Skype for Mac users who like to group all their chats into a single window, this might be a helpful tip for you: Skype’s chat drawer allows re-arranging your chats simply by dragging and dropping them around. If you want to change the order of chats (take the less active ones to the bottom of the list, for example), simply grab the chat or Contact and drag them where you like.
To start a new chat with someone, all you have to do, is drag them from Contact List window to a chat drawer – it opens a new chat and you can start typing. For sending a file, simply drag a file to any 1:1 chat or chat with multiple Contacts in the drawer. Releasing a mouse button will then start the transfer.
