When you have many conversation tabs open, not all of them can be visible at the same time in the tab bar. This is a problem, because it is easy to miss new messages that arrive to tabs that are not visible. This plugin tries to solve this problem by moving a tab to left whenever a new message arrives to it.
When a new message is received, the currently open tab is moved to the leftmost position in the tab bar and the tab receiving the message is moved immediately next to it.
