Changeset [21e4f94ab467923c6c4de93895c47463f58303f3] by Robert Buels

move text-filtering control to be next to and aligned with the grid, which is an important visual cue. also, refactor how track selector layout is done, putting all decisions about the position of each element in the main layout in the main render() function.
