Option to show widgets on multiple (or all) Tabs

It would be helpful to be able to display widgets on multiple (or all) tabs.

I often create a kind of control bar with signals I want to have permanently in view and important buttons like start/stop.

Once you have created such a controlbar and connected it to the corresponding signals, you can easily copy it to other tabs. However, it is tedious and error-prone if something changes later and this change is not repeated in all tabs.

Suggestion: You can indicate at a widget on which tabs it is to be seen. Or that it is to be seen on all tabs.

The widget is then seen on each tab in exactly the same place. If you change something in the widget - e.g. the assignment to a channel or the position - this will also change on all other tabs.
