That's a cool and long over due feature SooS for all comics apps. The thing I like about the article is its not owned by one comic source such as comixology, marvel, DC, darkhorse, etc... which from reading the article seems like could get integrated for powfolio android users once they add the download feature. Must be a way to do it while streaming too, that would be cool.
To be fair, I'm sure we could add a lot of other technology that powfolio doesn't have that Google play books has - lots of integrated Internet aspects such as wikipedia while reading; ability to change style of text; and other search features, etc...
But I like that feature and would be cool to see if they could integrate it somehow. Docg
