Sony has updated the Digital Comics Reader for PlayStation Portable.
You can read instructions about how to download the update on the PlayStation website.
Version 2.01 allows you to delete comics, which will be better grouped in collections, although all deleted content can be downloaded again free of charge. Database tweaks mean flicking through your collection should be much snappier too.
Sony's added support for right-to-left-read comics (Manga) as well as a thoughtful feature that offers to take you to the next issue when you finish a comic.
The MP3 player has also been updated to support more music formats, and audio clips have a progress bar and are not interrupted by page turns.
Finally, Sony's made some cosmetic changes to keep everything looking fresh.
