Coming from a Post Audio world where I work with audio clips mostly, not music creation, would like the option to show only the Time ruler and hide the default beats ruler. This would apply to the Clip and Track Timelines Details at the bottom as well.
As a further extension, being able to display one of the usual set of SMPTE time rulers (24p, 23.976, etc), would be helpful when using Bitwig in a Post environment, especially WHEN Bitwig gets video support.
