Server browser
Everything on the header at once, in a screen that has to share the space.

Resize, reorder and two level sort come from the header, and a text box above the table feeds Set Filter Text. Beside that there is a detail pane following the selection, a kit of 9 slots whose cells drag onto each other, and a feed that appends and follows its own tail.
One screen, not three
A server browser puts the header, a detail pane and a live feed on one screen, which is where you get to see how they share the space.
How it's wired

Three tables and three models: the list, the feed and the kit. The cells are drawn from maths. The kit binds On Cell Dropped and swaps the two slots itself, because the table moves nothing on a cell drop. The screen sets no Table Id, so its columns start as authored every time.
