That would confuse me even more to be honest. A submission that people discuss and reply to is not what I would think of as an article - to me, that would be more like a standalone publication.
I do feel like using different terminology could help in understanding how this all fits together though.
Love Nova Launcher! It offers so many customisation options, particularly in terms of home screen and app drawer layout, icons and fonts.
I remember a few years back when my phone was stolen (I accidentally left it in the back of an Uber) and I was forced to buy a new one. The relief I felt when I started up the new phone, signed into Google and straightaway saw my familiar home screen, courtesy of Nova Launcher.
I guess I was surprised so much was still there given I didn't do a formal backup / transfer between old and new phones, but that's the beauty of the cloud! :)
Edit: Also @distantlight, agree with Cube ACR - I have been immensely grateful having an easy way to record calls. It has a button to allow you to start and stop recording in the middle of a call so for me, it was piece of mind, especially during legal scrapes! But as another commenter has said, I feel like it stopped working at some point so no longer have it installed..
