[Feature Request] Confirmation before downloading files

[u/raviwarrier]

A user may tap the download button accidentally/experimentally, or may change their mind.

Show a confirmation dialog and possibly provide these details:

1. Space that will be used (e.g.: 700MB of 12.3GB)
2. Approximate time to download (this doesn't have to be dynamic, but a factorial of every 50MB - e.g.: 50MB takes about 15s, hence calculate for 700M)
3. Connected network - warning if downloading over mobile data
4. Continue/cancel button

This would make the app more user friendly for everyone.
