[Feature request] Download manager & notifications

[KaKi87]

Is your feature request related to a problem? Please describe. When trying to download a file, there is no immediate confirmation that it started, when going back to homepage or switching to other apps, there is no way to track progress, and in any case, there is no way to pause or cancel.

Describe the solution you'd like

1. A download manager, that lists all active, completed and failed downloads, allowing to pause, resume, cancel, retry, and open download folder.
2. Notifications for each download in progress or failed state and allowing same actions as above.

Describe alternatives you've considered None

Additional context None
