I'm a customer, and one thing that I think would be helpful would be to ensure that notebooks launch inside of the storage folder. In fact, I'm not sure there should be any folders other than the storage folder and another folder labelled to tell the user this data isn't going to persist, or is volatile.
I really like a lot of the features you have in place, but had weird things like files disappearing, git repos being erased except for folder name, etc.
That being said, I think there's a lot of value here, and once I defaulted to using only storage, had less issues with Gradient. I think the concept behind your company, seems to be democratizing the devops needed for getting on-demand compute, and I dig it.
Hit me up privately if you want to talk more. There's some potential ideas I'd like to discuss with you involving my employer and potentially augmenting our product with yours (and bringing customers with us). Hope that last statement tells you that despite the warts I've experienced, I really admire what you have accomplished. I'm a big, big fan of intuitive UX that simplifies high-value tasks, and I think you've achieved a lot there.
