nice to have a filter to filtered out the 0 count records. I still want to see all records in this app ... I prefer not to see a count icon box if the count is zero. Reduces the noise on the view.

Also, have more color options; include the option of opacity. (like the single select color options).

Or have the ability to have two colors ... a grey one for count zero records something that blends in more, and the regular color option for counts above 1
