Adjust card view zoom level (LunaCE)
This tip is only for HP TouchPads running webOS 3.0.5 and LunaCE 4.9.5 or higher
Although the size of the screen on the TouchPad is much larger than that of any webOS phone, the size of the apps that are visible in the cards and stacks that are shown in card view are no different. This is not exactly an efficient use of screen real estate that should allow you to see more of the apps that are available to you. With the released of the Open Source "webOS Community Edition" for the HP TouchPad (not to be confused with Open webOS), the group at WebOS Ports was able to give you more control over how the cards and stacks appear on the screen as part LunaCE (pronounced "lunacy"), available in Preware. Note that LunaCE is currently in beta so you will need to go through the process to set-up the beta feeds in Preware, which can be found at testing.preware.org. In addition, you will need to have Tweaks installed on your TouchPad to toggle this new feature.
Just as you can adjust the Stack overlap spread amount to view more of the apps within a stack, LunaCE also gives you the ability to adjust the zoom level of the cards and stacks on the screen. Once you go into the "Luna" section of Tweaks and toggle "Card Zoom Gestures" to YES in the "GESTURES" section, you can then perform a two-fingered in or out gesture when in Card View to adjust that zoom level. You can keep the zoom to a level where you only see a sliver of the adjacent stacks to the current one, or zoom out to be able to view up to 5 stacks at once in landscape.
The one thing to note is that if you also have the "Stack spread gestures" toggle also set to YES, any time you pinch-in or -out to zoom on a stack with more than one card will prioritize the stack spread gesture and not the zoom amount. You will need to swipe over to a stack with only a single card first and then perform the zoom gesture.
