Better yet, would be to have a link that opens a window which dispays a verticle list of all the HTML attributes available to the selected object in one column (left) and a right hand column where the value of that attribute can be set. However, you also should read and consider what I've included below (I wish there was a way to attach a file here).

Tiggr Mobile App Developer:
Needed Properties and Capabilities
Drag and Drop UI must include for all visible/display objects the capability of a) selecting individual or groups of objects that have been dragged to the work area, b) positioning of the object(s) anywhere in the work/template area and c) resizing the object(s) by with resizing handles. The x,y,w and h values in the Properties panel would change as each of these variables is adjusted by drag and drop. Often one gets a better feel for the visual design of the user interface by using such capabilities. Like so many other drag and drop development IDEs I’ve tested lately (such as Android’s App Inventor) yours snaps each object added to the work area into the next available place.
Ideally, what we need is an extremely flexible IDE not unlike, but even better, then that provided in Microsoft’s Visual Studio, which allows very rapid and complete development. I’m afraid yours and so many others don’t even come close to the ease, completeness (of properties, methods and events) and flexibility of that development system, which I’ve used professionally since the beginning. I know you are not finished developing this product, but you could learn much by mimicking the thoroughness of the VS IDE. Below is a beginning of my detailed suggestions for the objects provided. It does not yet include all of the objects.
BUTTON PROPERTIES:
ALL properties should be modifiable through assigning the value(s) of explicit or named constants or variables of the appropriate type.
Style (values = 2D/Flat, 3D)
Change “Position” to “Horizontal Position (x) and Vertical Position (y)
Width (w)
Height (h)
Change “Theme” to Color (full list of colors, color picker or user sets RBG values)
Text/Label Font (pick list)
Text/Label Font Size (pick list and user entered – either)
Text/Label checkboxes; one for Bold, one for Italic.
Text/Label color (same as for “Theme” above)
Text/Label background color (same as for “Theme” above)
Text/Label background transparency (values from 0 to 255 with 0 fully transparent, 255 solid) – this would be useful/necessary for the following added property.
Background Image (to display behind text).
(button) Shape (values of Square, Rectangle, Circle, Oval)
BUTTON EVENTS:
Click (already have) – equivalent to Tap or single click.
Press (touch and hold) – longer than a mere Tap and equivalent to double-click
Swipe (sliding across the button)
Each of these would trigger corresponding methods in which the developer would define the actions to be taken. Any combination or all of these could be set to on/off so that a single button could be employed for different purposes. When an event is set to on/active, the framework for the “coding” would be written and stored (developer would open a manual editing window or you would develop a form the developer would complete to describe the action to be taken as a result of the event)
I will continue this later – have other work to do.
