I've been getting a few complaints/request to be able to rearrange tabs or to place certain tabs on the front page. I'd like to clarify that it is possible to rearrange tab order in G-Whizz! This capability has been present since version 1.0 of the app.
Rearranging tab order is actually a standard convention in all iPhone OS TabBar applications (like G-Whizz!) that contain more tabs than can fit on the front screen. Simply click on the "More" tab on the right, then click on the "Edit" button in the upper-right-hand corner of the "More" screen. This will then bring up another screen that displays all available icons on top, and on bottom displays the icons that will be present on the main screen. Simply drag any of the icons from this top group to the position on the bottom row where you would like it to reside. You can also drag icons on the bottom to different positions. When you are done, simply click the "Done" button and your order will be saved. That's all there is to it! See screenshot below for an example of the "Edit" screen.
