Change tab name to selected menu page

[BOverdevest]

When having multiple pages open on Domoticz, all the tabs have the same title; the name of the location as set in in Options.
It would be nice if this could be changed with the menu item opened, so it is easier to move from tab to tab.
Names would then be Hardware, Log, Scenes.

Where should this be implemented, in Domoticz itself or in the theme?
