As you may know, Canonical is making big efforts for releasing a new Ubuntu Touch OTA Update each six weeks, in order to implement new features with regularity.
The Ubuntu developers are currently working at a download manager to add by default on Ubuntu Touch, starting with the OTA-9 Update. The software would permit the users to download files directly from the browser, without having to send them to other apps, or download a file once and send it to multiple apps without needing to redownload each time.
The Ubuntu Touch OTA-9 Update is scheduled for release on January 20, now being too early to know about the features that will get implemented.
As a reminder, Ubuntu Touch comes pre-installed on Bq Aquaris E5, Bq Aquaris E4.5 and Meizu MX4, but is also officially supported on Nexus 4 and Nexus 7. While still young, Canonical is constantly working at it and releases a new update every 6 weeks.
