1. Is this request related to a challenge you're experiencing? Tell me about your story.

When using "Browser-side download to a local folder" for batch downloading, the only feedback is a snackbar that says:

"Batch download has started, please do not close this tab..."

With a spinning indicator and a "Details" button. There is no information about:

• How many files have been downloaded out of the total
• Download speed
• Which file is currently downloading
• Estimated time remaining
• Total bytes downloaded

For large downloads (e.g. 360 files, 2 GB), this means the user has no idea if the download is at 1% or 99%, whether it's stalled, or how long to wait. They just see an indefinite spinner.

Requested feature: Add progress information to the batch download snackbar:

• File counter: "142 / 360 files downloaded (39%)"
• Current file name being downloaded
• Download speed (MB/s)
• Progress bar
• Total bytes downloaded

2. Additional context or comments

The information is available - each file download goes through fetch() which could be tracked. The browser's ReadableStream API can provide real-time byte-level progress for each file.

I've implemented this as a workaround by intercepting fetch() in a custom footer script and injecting a progress tracker into the snackbar. It works well and shows that the data is readily available - it just needs to be surfaced in the UI.

A native implementation would be much cleaner and wouldn't depend on intercepting browser APIs.
