Mousing over Dynamic Panel should display tabs.
As I work with Dynamic Panels, I find that I am spending a great deal of time clicking in different areas to select the correct item or layer. It is particularly difficult to select the Dynamic Panel so I can view the tabs across the top. Users have to select a very thin line, very difficult if there are many items within the Dynamic Panel (a very common scenario). I keep accidentally selecting items within the panel, instead of the panel itself.
I would suggest making it much easier to make the tabs across the top display (the most common reason for selecting a Dynamic Panel). I would suggest the following:
1) When user hovers mouse over Dynamic Panel or the area where the tabs are, the Tabs display.
2) When user selects a tab, it selects the layer.
3) (not sure about this one) When user moves mouse away for Dynamic Panel, the tabs disappears, perhaps after a one second delay.
I think this will make it much easier to work within a Dynamic Panel.
