Display arrange ambiguity

I think the images attached show better than I can ever word it however the
issues, with reference to the obvious ambiguity shown in the images are:

- Changing monitor arrangement is trial and error because there is no way to
tell one monitor from the other.

- Changing monitor priority can look like you didn't even change the order
because the monitors are identical.

What needs to happen for this to be fixed:

1. The description of the monitors needs to contain a unique number or name.

2. The description of the monitors needs to contain the priority now that has
been added as a priority list and the priority list needs to show the unique
number or name for the monitors.

3. For large numbers of monitors like this it is desirable that when you click
on "Identity" that the numbers say up until you click to remove them. 2-3
seconds up is not nearly enough to be useful. Also, the 30+ character
description could be replaced with something like a single fixed number for the
display and perhaps another number showing it's priority - something more
useful to digest.

4. Ideally you could right-click on one of the monitor images that you use to
arrange them to set which one is primary. And, by extension set other
attributes that way.

Finally, there is an additional issue that sometimes moving a monitor or
changing some other parameter will cause all the monitors to pop to the same
resolution which ends up being lower than any of their native maximum
resolutions which is usually undesirable. If it's going to pop to some default
it would highly desirable to make it the maximum resolution of the monitors
rather than some arbitrary lower resolution default. This would make this
particular bug essentially transparent to almost all users since the default
would be what is desirable.
