So I was very pleased to find the Darkgate Comic Slurper, which brings pretty much everything I read (and a lot I don't) into one configurable page. All you need to do is go through the site's comprehensive list, choose the comics you want to read, and they're all brought together in one place. All you need to do is scroll down. And if you read as many comics as a I do, that can be a long scroll. But it certainly beats click on each bookmark, one at a time.
One thing to note, as the Slurper is cookie based, suing a cookie to store your subscription information, subscriptions don't transfer between pages. That's of course if you read your comics in a browser (my preferred approach). There is an alternative route - once you've generated your comics list, all you need to do is generate a Comic Slurper RSS feed and subscribe to it in your favourite RSS client - and updates arrive as the comics update.
Definitely a Very Very Useful Site.
