LGTM 💯

[xmudrii]

Looks great to me, great job! 🎉 💯

Maybe you could think about changing ArgTag to use ArgTagName so we stick to some standard. Also, maybe it could be good idea to use ArgTag everywhere instead of ArgTagName.

One more 'maybe maybe' change could be moving ArgDropletIDs under ArgDropletID to keep some readability/consistency, but it's good this way too.

Once again, really great job. 💯

many thx for your review @xmudrii I addressed you feedback @ 3d2ac71
