Sorry if this sounds a little rude, but how much trouble is it to just click the reading list panel? The mobile app is catered to mobile readers, including new mobile readers. If new mobile readers come to the app and see an empty reading list, they will be baffled (especially considering those new readers are often not even members, and maybe never will be members; they just come online to read, and sign up for Tapastic when they want to become more dedicated readers). The Daily Snack is, TBH, a great front page just because, you know, most people are on the mobile app to read, and Tapastic is pulling in new readers all the time, readers who they hope to make subscribers out of, and they can only do that by showing them daily comics that they can read while on the bus, at work, etc.
Although I do agree it would be nice to see replies in some fashion, most of the time I'm able to easily access these by checking my Gmail, which is linked to my phone, which is linked to my Tapastic, so I'm often able to get notifications that way. A little roundabout, but it works for now
