How find "hidden" code in web project (placeholders, widgets, etc)?

[jonstrong]

I just started experimenting with some 3rd party web templates, and while waiting for feedback from the developer, started to explore on my own to see if I could figure out how text objects on a hidden page become image files for the included WowSlider to display. I still haven't figured that out just yet, but...while investigating I've been looking at properties of seemingly related objects, and noticed a name "htmlclass = hide recipient-email" assigned to a few otherwise innocent looking placeholder items.

So...I was hoping to understand what this is intended to accomplish, and started looking for other placeholders that might hold embedded Javascript. So far, no luck.

This raises a couple of questions for me:

1. Is it possible to search through an entire project (I'm using Designer Pro, but this would apply to that or to Web Designer) to locate ALL placeholders, anywhere in the project?
2. Is there documentation available to us that illustrates how widgets are built for use / integration with these Xara products?
3. Any insight into a way of using WowSlider where I can essentially have it convert text objects, on the fly, into the image objects it displays?

While I like being able to add in extra functionality and features via widgets and placeholders, I'm also concerned about "black boxes" winding up embedded in my projects, perhaps via these 3rd party widgets and/or templates.

Thanks for any thoughts on these.

EDIT: Well, I figured out the WowSlider text question. Turns out that the object holding the text that winds up animated in the slider was in a copy on one of the variant pages that I had missed editing (and that was the one showing when I tested the page... DOH!). I'm starting to think perhaps the hidden recipient email address will turn out to be associated with some contact-us logic, but I'm not certain yet... Again though - if anyone knows how to locate any/all placeholders in a project, I'd be very interested in this, as well as learning about how Widgets are developed / coded, etc. Thx!
