If HP wants webOS to be a competitive mobile ecosystem, the platform's app store has an awful lot of catching up to do -- but in terms of raw features, it sounds like the company plans to get with the program soon. PreCentral attended a developer presentation at MWC 2011 where HP showed off a brand new version of the App Catalog specifically designed for the tablet-friendly webOS 3.0, and found it will come with a handful of features that should make it eminently more useful. As you can see in the image above, there are presently four tabs, but two of them are worth calling out: the "Browser" is said to be a magazine-like interface for browsing through apps, while the "Saved" tab lets you bookmark apps you're interested in to consider for purchase or download later on. Perhaps more importantly, the process of actually paying for programs should be streamlined quite soon: HP told attendees that carrier billing and promo codes would find their way into the webOS App Catalog by summer at the very latest, in time for a webOS 3.0 launch, which suggests that it could possibly hit smartphones even a mite sooner.
