[Qt-creator] Help with plugins

[Jochen Becher]

Thank you for the clear answers. I didn't know that the Design mode
supports adding more editors than the Widget and Qml designers. My
plugin is a simple modeling tool (no a full featured UML tool but
something that will help us documenting our software). Fits perfectly
into the Design metaphor so I will changed the plugin to use the Design
mode.

Regards, Jochen

Before you ask: yes, I plan to publish it under GPL later.

We are usually trying to avoid the addition of modes, each and everyone is hotly discussed (already the "Design" mode is questionable, but the result of the editor manager not having any concept of editors that require "full screen").
