Would it be possible to add a "Click-through" functionality which could be turned on or off per window? It would allow selection through the window.

Many windows are informational and require no interaction beyond being visible. It's great to have them up, but they then get in the way of selection occasionally.

Or, better yet, all areas that do not take input would then allow selection through them.

If you want to see an example check out Shadowbane. While it did have it's numerous problems, it had a decent implementation of this.

Thanks!
