counter disappear because there is no reason to include it in Gem.
you can make a counter abstraction in few minutes.
there are plenty of them.

it's sad to hear that you want to switch to vvvv because of a missing counter.

I know, probably vvvv is the better choice to do this - but first i want to try it with GEM. i started with two screens, two pd instances, two gemwins framesynced over netsend/receive on one machine. for edgeblending i use pix_takealpha and a matching tif with alpha channel.
