Overlays appear on hover and display additional context information.
They provide "shortcuts" on desktop. Only one overlay be visible at a time.

Overlays can contain tables. Table rows in overlays have a height of 28px.
By default, the overlay should appear at the lower right corner of the cursor. If the available space can't accommodate the overlay, it should appear on the left. The same principle applies to the top corners.
If there is no space on the left or right corner, the overlay should be centered on the bottom line of the cursor.
To avoid that the overlay pops up when you pass triggering elements, the overlay should have a small delay of 100ms. The fade-in and fade-out animation should both last 150ms.
Overlays can hold interactive elements.
Compared to default overlays, the position of interactive overlays can be fixated with a click. This enables users to click links and buttons within the overlay.
Interactive overlays can only be used on elements with no other interactions. This overlay can also be used on mobile devices.
Overlays that use a two-colummn layout can be responsive.
Here are some examples on how the overlay could be used.
The information visible in the table overlay can also be found within an expanded table row. The information belonging to the hovered column will be highlighted within the overlay.
