Ubuntu asks for installing various websites' webapp versions by prompting when I open the particular website. As of now, I've installed WordPress, Facebook Messenger, and Reddit. But I don't see any use of them.
I read a post on Canonical regarding this, and it seemed pretty cool. Notify OSD, native HUD and other generic Ubuntu-specific frameworks are promised to be fully exploited with these integrations, but in practice, it seems just talk and no action.
For example, when I search Facebook in Dash, and click on the webapp Facebook Messenger, it just kicks the browser and opens a new window with facebook.com (even if another window is already open).
All that seems to be working is some FM website that is of no use for me.
I want to know what are benefits of these webapps integration and how do I use the webapps I've installed (let's say the Facebook one).
Other than just creating shortcut in launcher you won't get any feature that you would not get in regular browser.
I did once, the native browser does not give you many features like bookmark, add-ons etc. It will just create a shortcut in dash that you can search and just launch without typing URL
