Issue:
Since 3ds Max 2017 it's not possible to see if a uv-island has already been assigned to a group,
other than selecting it and then clicking the select group button. This makes working with groups a laborious task.
Even though the versions prior to 2017 show the group id which a uv-island belongs to,
it is still not obvious which other uv-islands make up the group, other than clicking the select group button.
Idea:
The ability to toggle a visualization of the different groups would be a nice feature.
This could be solved by drawing the outline of the bounding box that is formed by the grouped uv-islands.
Different colors per outline will clearly differentiate a group from the others.
Additionally the group id could be drawn at the center of the bounding box.
