Multiple Table Elements and Square Wave LED

I’ve noticed a couple things about Groov that I either don’t understand or Groov can’t do yet.
First, why can’t the Text Area gadget display more than one element from a table? Sure would be nice if it could. Maybe select a range of elements, select specific elements or select them all. If more elements can be displayed than the window is sized for, maybe show a scroll bar?
Second, I’ve noticed the LED gadget doesn’t seem to function properly when tied to a tag that is activated by the “StartContinuousSquareWave” function. It surely doesn’t change state that follows the square wave. Using a 1Hz 50% duty cycle to flash a light. I could understand it not working for high frequency square waves, but why not low frequency?

Any suggestions?
