How to write an add-in for creation of Windows forms but save them as XML?

Hi,

Here is my problem: I'm trying to create an addin for creating custom windows forms but to save / restore them to / from XML.

Basically, I should create a view with two tabs: the first tab will be the the SharpDevelop's standard form designer and the second one will display the SharpDevelop's XML editor which will display the XML representation of the form being designed.

Any changes done to either tab content will be reflected into the other tab.

The extension of the file will be ".imform". On the left hand side, all the forms are grouped within a project (project tree), when double clicking on a "*.imform" item, the two tabs view should open to edit the form.

Any help would be appreciated.

Many thanks.
