When rescaling the thumbs with the slider, it would be helpful if the user could optionally choose a combination of the following behaviors:
- 1. Rescale the thumb label fonts with the thumbs.
and
2. Hide/show thumb label components according to thumb size.
The user would prioritize visibility of thumbnail labels in the label definition dialog. Perhaps a rule as simple as: "hide/show labels from the bottom up when scaling thumbnails" would suffice.
