There is an anomaly regarding how Fullscreens and External Outputs are assigned to Inputs.

If it is set by the dropdown meny offered in the Fullscreen/External button the selection is tied to the Input's number. Which might become a disaster if the Input is moved to another position. On the other hand, if it is set with a shortcut and the "Assign Shortcut to Input Number" is unchecked, it is tied to that specific Input whenever the Shortcut is used. But if the Input is moved, it is no longer used for that Fullscreen/External Output.

I would like to have a corresponding option for the dropdown way. For backwards compatibility with the checkmark checked as default.
Furthermore, if a shortcut (unchecked Input Number) is used to select the Input, then the selection should not change when the Input is moved. (This new behavior might cause some backwards compability problems if people expect the current behavior...)

Slightly related to this I think there is one/some old feature request/s to have the dropdown menus when setting Fullscreen and External Output display the Inputs name (and number) instead of just "Input #". (can't find them so I might be wrong, still worthwile considering...).
