Working demo for testing

Hi,
Please let me know if you have time or functionally limited working demo of your extension which I can use at my site for testing?

I'm wondering if it's right solutions for my needs....

What I'm trying to achieve is to add my own created vector map of factory site, with outlined some specific places.
What is important to me is if it's possible to make groups for items (for example for changing room, for AED places, etc) and show/hide them with radio/check button by users.
Also I'm wondering if it's possible to get some data from Joomla Custom Fileds, or your other extenstion - Drop Table - this will be much easer to collect all data, and to show it not only in created maps but also as a text table.

Please let me know, if there is possibility to download your extension for testing.
Regards,
Karol
