With my recent theme I found out how to do this. Go to "Theme the Home Screen" in the Inspector window. Now add some Zen apps, they will appear like normal on the left side with text names and tabs but don't worry as they can be removed. Now, click on each Zen app and scroll down in the Inspector window and deselect "Show Text" in the Properties section. This will remove the text names. Select "Reposition Applications" (below the application list) and now you can place the icons as you want on the bottom of the screen. Two things you want to remember for each Zen app:
- Check "Use Device Application Order", this way the user can modify what app they want to appear. Not critical but will avoid the questions later.
- Maintain your order. The first Zen app in the application list should be the first one on the left and so on down the line.
