Use Fonts and Color to help discriminate columns:
Values that come from the TC Master are now in black boxen (ToDo: use gtk theming)
Reduce the number of columns, to improve legibility:
Consolidate the Slave's current TC chase value and Delta (offset from Ardour current TC)
Consolidate the last message received, and how recently it was received
Remove Collect checkboxes (just disconnect the port if you don't want it to run)
