It's great to hear the news about the Smith Chart.
Your attempts to rotate text had been very demanding, and the restrictions given by the resolution of the display are limiting the posibilities.
If the available libraries are limited, extending them results in an extra project.

Maybe an approach with zoom functions (showing labels after zooming in) will be interesting, but this will again distract from the Smith Chart himself.
Do you want to show the current status? (screenshot?)

Here's a screenshot of the Smith Chart so far. It seems just about the time I can see the end game, I want to add more features to it. So it is not completely up to my expectations, just yet.
