I just got back into even and saw the feature preview. I LOVE the new UI, but this one bug is driving me nuts. The info button on all my panels is no longer situated next to the scroll bar, but underneath it. A bigger panel size does not drag the button out from underneath it.
Here is a screenshot:
So often when the scroll bar vanishes, if I do not click the extreme left edge, I hit the invisible scroll bar moving my entire list making me have to go find the item again.
