Firstly, thanks for a great library! It has been amazingly useful.

I would like to display a counter variable of packets received from a CAN interface. Although it is not critical that the display be updated with every single increment of my counter variable, I do prefer it update several times per second. Can this be done efficiently?

As a POC I made a simple tview.Box with a drawFunc but this seems quite CPU intensive. Is there a better way to accomplish this, perhaps a TextView or some other means where refreshing can be done more efficiently?

Ultimately if I have to refresh on a longer interval, well them's the breaks, I suppose. Thank you again!
