Current font size of iteration numbers is too small for me and I cannot change it. I can enlarge the iteration bubble but there are some issues I experienced:

1. I expect that it stays as circle and doesn't change it's shape to oval

2. Font size of iteration numbers would become bigger as soon I make the bubble bigger

3. Next bubble I create remembers last bubble's changes.

It's really good feature with iterations but it's not convenient to use it right now
