full spec sheet for the Topaz not good enough for you? Fine, Pre Central has managed to dig up another little document from HP's 2010 archives, this one delving into tablet-specific UI elements in webOS. The first notable thing is the inclusion of more sophisticated gesture and tap controls, with double-tap, tap-and-hold, and even two-finger tap-and-drag actions serving some unspecified functions in the tablet version of the software. Tabbed browsing also makes an appearance, alongside an auto-expanding email client and a page-turning element, all of which may or may not be in the final build shipping with the final devices. Until finality is reached, however, the source link is your best buddy.
