@lonnieezell , I was wondering about how to mark duplicates.
If I was to make a slim column all the way to the left, populate it with a red colored capital "D" when it's a duplicate, and on hover it would explain that "This query ran more than once", would that be in line with your original vision for this issue?

@danielTiringer Originally, I was thinking the background for the query would be slightly different, but I think this is a nice simple solution. If we find it doesn't stand out enough down the road, we can always modify how it's showing.

This is how it currently looks:

The first call of a query is not marked, only the consecutive ones. And when one hovers over the row marked with red, the title text shows in a small popup message.

I think that orange makes things too difficult to read. A simple grey that's just a few shades darker than the background (or lighter for the dark theme) would work I believe.

For the light theme, the gray from the CI welcome page would probably work well: F7F8F9

Actually looking at it again - there's a hover color in use already. What do you think about just using that color for this?

The hover colors look good to me. Thanks for the recommendation, I'll go with those.
