Enable mini-card view on the TouchPad (LunaCE) 3
This tip is only for HP TouchPads running webOS 3.0.5 and LunaCE 4.9.5 or higher
LunaCE (pronounced "lunacy"), the homebrew update for the TouchPad by WebOS Ports is based off the Open Source "webOS Community Edition" released by HP (not to be confused with Open webOS). It contains a number of enhancements to the TouchPad, including those on how you are able to interact with open application when in card mode. You now have the ability to adjust the overlap level of cards in a stack and the zoom level of the cards, but LunaCE has also brought back a feature that used to exist in webOS 1.x but was removed in webOS 2.0: the mini card view!
By tapping on the area below an open card or stack when in card view, the zoom level of the cards will adjust to allow you to see a mini view that will show up to 5 cards or stacks at once. Tap below the cards again and the apps will return to the normal zoom level. If you also have the "Card Zoom Gesture" tweak enabled, the mini-card mode will remember your custom zoom level and use that instead.
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. Once you have both of them installed, you just need to go to the "Luna" section of Tweaks and toggle "Enable Mini Cards" to YES in the "CARDS" section to activate this feature.
