These controls are awesome! Thank you very much!
I'd like to ask for a change and a new control, if possible.
First, for the Time Stamp control. When the increment/decrement buttons are visible, they appear to the left of the control, outside it. It'd be nice if they were within the control and to the right, similar to numerical ones.
Second, for the Combo Box. It'd be nice to have the selection arrow within the control, similar to the Enum and Text Ring ones, instead of in an external box.
With these two changes it'd become very easy to pleasantly align controls vertically.
