I just got a twiddler4, upgrading from a twiddler3. The "three configurations" feature seems nice, but flaky - AFAICT, every time I reconnect, I have to switch from the default layout back to layout one; does it really not remember?
Also, if I try to switch to layout 2 (which is empty), it seems to "crash"; no leds, no input. Sometimes plugging it into a computer fixes it; other times, it seems like it needs to wait a few minutes.
I suppose a workaround is to just duplicate my first config into the other two slots, but this seems like a pretty major oversight...
