Hello Alistair, Alexander,

Thank you for the detailed information about Cambalache and Merengue.

To answer your question about running on X11 with Nvidia drivers: I have 
tested the Cambalache UI designer itself on two of my own machines 
running XFCE on X11 with the proprietary Nvidia drivers. In both cases, 
it worked without any problems for me.

Also, I want to note that there should be no problem with developers 
using different tools. The UI files are compatible. One developer can 
edit them using Cambalache, and another can use Glade. This makes 
collaboration easy.

So, I am confident I can use it for development in our X11 environment. 
I have now started creating the welcome application.

When I have a working version that is ready for testing, I will send it 
to this email thread as a Work-in-Progress for your review.

Thank you for your guidance.

Best regards,
Ajrat Makhmutov
