WP Super Cache Manager has a number h3 section(i.e., WP Super Cache Status, Cache Contents, Garbage Collection, etc...). Each is a link when clicked that collapses the fieldset.
I see three problems here from a UI perspective when hovering over the h3.
- There is no visual change to indicate it's a link other then the pointer. Color change or other clue would be better.
- There is no tool tip (e.g., Minimize or Collapse) to clue the user in.
- The clickable area extends all the way over to the right edge of the screen. More then once I have accidentally collapsed a h3 fieldset and been alarmed as I didn't understand what happened at the time.
