Make line indicator for installed add-ons in the Supervisor thicker

The request

For the add-ons in the Supervisor, the line that represents the installed add-ons is a little too thin. I would suggest making it a little thicker (Example 1). Another option would be to have the line on the left (Example 2).

I personally vote for option 2. The horizontal line always looks confusing to me, as if it separates the entries in the columns into groups.
