Allow separate pre- and post-SSS competition screen layouts
When in a competition you would typically be either thinking about getting a good start (before SSS) or planning your final glide (after SSS), but not both at once. On a competition screen, it would be nice to be able to use the same screen area (start widgets "on top" of goal widgets, same x/y and size) to display the start-related widgets (Time to start, Time at start, Speed to start) before SSS and the goal-related widgets (Distance to goal, Altitude over goal, Glide to goal) after SSS.
It doesn't currently seem possible to do this on a single screen. While the start-related widgets are blank after SSS, their background is still drawn and will hide any widgets behind them. If they are set to transparent, any goal-related widget behind them will show through even before SSS.
If the goal-related widgets could optionally be hidden before SSS this would enable them to share screen space with the start-related widgets.
Alternatively or additionally, the "Hide title and unit when nothing will be displayed" option could be changed to "Hide widget when nothing will be displayed". By itself, this would enable start and goal widgets to share screen space if the foreground start widget is set to 100% opaque.
