Timeline tabs feel inconsistent with rest of UI

Currently the timeline tabs have curved edges with a gap between it and the top panel and it feels out of place with the rest of the interface.
Every other area in the interface has only a 1 pixel margin between it and another another area and curved edges are used very infrequently. It just feels like something like this would be more consistent and saves 2 pixels of space.
Obviously those 2 pixels aren't super crucial but they add up the more timelines you have stacked.
