We've been kicking around ideas for managing files on volumes. This is a common problem – it's actually more difficult than you'd expect because "securitah". Once your volume is mounted in one of your VMs, we can't run tools outside the VM to let you manage the file system. On something like k8s with vanilla Docker, we could. But no one should run multitenant Docker.
It's not really an excuse, just a reason it's taking longer to solve than we'd like.
The errors on the web UI sucked. These have improved drastically in the last three months (because we have smart, dedicated people working on fullstack for us now).
