Ok, CD appears to have an issue when you get more tabs than can be displayed across the top (possibly due to the rectangular design of the tabs, I don’t know). When I have say, 100+ tabs open, it does not a) show all of the tabs, nor does it b) allow any scrolling to the right to GET to the tabs not displayed.
When I have the exact same tabs open in Chrome, they are ALL displayed, I don’t even have to do any scrolling.
This is a “killer” issue 
(I didn’t see it listed, but I can’t be the only person experiencing this).
CD Version 28.1.0.0, Win 7, x64
Thanks!
