am really interested in this one. Just need to find out if anyone has worked on that or not.
If not - I will give it my best and create such a mod.
Also, since I just discovered Silverstripe this afternoon - yes - read over every page on the website - I decided it is my salvation after a long, frustrating search for the perfect CMS [tested countless installations] - I did not see anything like a html wrapper. Maybe I overlooked it or something similar.
Suggestion for these 2 things I'd very much appreciate. :)
I haven't tried this but I guess you could create your own page type and have some form of iframe to display the specified URL. You would need to create a template for this page type that would be parsed to present the defined instance.
