Default skin based settings option

Hi,

I am thinking about an addon writing, and I want to create a settings option, where the user Can force the addon’s looking for example to Thumbnail view.

Well, I have done this for Confluence at the past, but as I have realised, the Estuary has absolutely similar view ids…

So is there a way to create a settings option (a type select) which is only active when the default skin is Estuary for example?

I hope, everything was clear, because my English is not top notch…

Many thanks!
