This is a small refinement of the user interface that would be helpful in some of the layouts with large numbers of panels open. It could be implemented in either or both of two ways:
- When the user clicks on the linkset letter on a tab, a list of all panels sharing that linkset is displayed. Click on an item in that list jumps you to that panel.
- When the user clicks on the linkset letter on a tab, all panels sharing that linkset are highlighted … brightened or flashing perhaps.
Bonus: it would be helpful for training and debugging if the index used for linking was shown.
