Tap the toolbox, tap the plus sign at the top of the toolbar, and choose from a list of preset toolbars or choose "New Toolbar" to create one from scratch.
To add tools to a toolbar drag and drop them from the tool library to the toolbar. If the tool does not want to "stick" try placing it between two tools rather than below the last tool.
* Some tools can only be added to a toolbar one time.
Drag tools from the toolbar down toward the trash icon on the bottom of the toolbar.
Tap "done" or the "x' when finished editing to save the changes.
