The Note Tabs plugin does the job. Well kind of, because I already tried it in the past. I thought about a bug as the tabs appeared on the left part of the window. Once again, I tried today... just to discover the screen part where the plugin appear should be configured !

Well, it’s not the correct topic, but the default is totally wrong ! (and apparently, I am not the only one thinking so, looking at its topic).

Anyway, once the plug-in appears on the top, I find the tab management a bit strange, and there is no option to configure them like I would like to... I will likely develop that a bit more on the plug-in topic.
