Great to hear that you have this problem, because in the evenings, I am working on a little extension of Pocket that automatically groups saved links by the length of content :) so it's not only me who has the problem, heh.

I have a lot of quality content marked for later and not knowing how long it is (especially when e.g. commuting to work when I have 10 minutes only) is rather annoying. And managing the list isn't something I fancy doing myself (we have computers for that!).

Drop me an email (in my profile) if you want to talk a bit more about this problem.
