Just an idea... It would be nice to have an option in Libervia for changing the behavior and relation between contact list / chat dialogs / tabs. The alternative behavior I think about is based on the principle "1 contact = 1 tab": - click on a contact in the contact list 1. opens a new tab containing the chat dialog with this contact or 2. select the tab containing the dialog with this contact (if it already exists); - the tab bar MAY be hidden if the contacts for which a dialog/tab is already opened can be idenfied directly in the contact list (e.g. "*" means "new message" like the current behavior, and "°" means "dialog exists")
