While not native but I believe there is a way to access Google Cloud storage with Transmit.

I've also been waiting for Google Cloud Storage support for a long time. Please add it, Panic! That's the only thing I'm missing.
I've been using Transmit for 10 years and had already moved to Forklift since the Transmit 4 engine was so slow.
Transmit 5 looks awesome and I only miss access to Google Cloud Storage which surprisingly only Cyberduck supports.
