Display amount of SRFIs an implementation supports

It's tricky to figure out the number by visual scanning and scrolling for a few pages while still tracking the right column. A small UX improvement would be to have a tooltip for each implementation showing the numbers:

Would it work to have the counter always visible as a separate row in the table? It could be right below the title row, or it could be the last row at the bottom of the table.

It makes more sense at the top than bottom and would require more thought about colors and placement of the description. The tooltip thing is less obvious, but avoids these issues.
