My Tapas bookmarks on mobile and desktop both go directly to the dashboard, so they're pretty much the only part of the site I see (aside from reading lovely comics of course). I visit it every day to read new comments and check if anybody's sent me a dashboard message.
My major gripe is that the "view desktop site" link on mobile is hardly honoured, it's constantly throwing me back to the mobile version of the site along with the intrusive "YOU DESERVE THE APP" popup. It wasn't so bad when the mobile site showed comments, but it's now a massive pain having to keep opening the app, navigating to my series, navigating to the page and searching through the all comments to find the new one. In simpler times I used to be able to just click the link.
Other than that, it's the same ol' suggestions: Ability to reorder/insert episodes, referral info, dashboard posts on the app, ability to change timezone and email notifications of dashboard messages.
With that being said, the Tapas dashboard is still waaay more helpful than Webtoon's haha!
