Row controls for Kinvey Databrowser

One issue we always had with the databrowser was handling actions available when a row is selected. Previously, new buttons just appeared across the top of the table - obviously not ideal. We kept running out of horizontal space, and the user had to run laps with their mouse from the row to the action buttons at the top.

This is our new solution - an overlay of buttons that appears below the selected row. What do you think?
