* Pens. Draw! has two pens. When you choose the current, a popup dialog comes up to change color and width. (Or try the eraser to wipe everything to nothingness)

* Volume buttons: Use the buttons as a switch pens short-cut

* Back button: If present, pressing this button will Undo a move. If not, a ‘Exit’ popup will show indicating the that next time it will exit the app. Draw! can remember up to 20 moves. [long press = Save]

* Background color is by default Black. But you may change it into any color in Preferences

* Flip n Shake. Turn it on and be able to quickly clear the screen by flipping and shaking the phone.

* Double Tapping. When turned on, double tapping enables you to quickly toggle between Panning and Drawing mode.

* Zoom. Draw! also support multi-touch. Pinch with two fingers and presto, the canvas shrinks…

* ABC. Make a word, press OK and draw a line to indicate where that should be drawn. Draw! supports gesture recognition(my personal handwriting that is) and voice recognition to input a word. Check out the graffiti pic somewhere on my blog.

* Red vs Blue. The idea is to beat the opponent by drawing more color on screen within a timeframe. With Draw! you can connect to another phone and play!. (Check out the youtube video on this website somewhere)

* Froyo. Need to free up space? In Settings->Applications, you can move the entire app to run from SD card. Alternatively, you can export pics to SD.

* Import. Got a pics you want to draw on? Try Import.

* Send. Use this to send the current pic to friends or sorts.

* Sets. There are 5 slots in the Gallery where you can save your drawings. Swipe up and down to switch slots.

* Flash. There is a way to flash all pics in the current set like an animation. Tap the screen to set the pace.
