[Suggestion] Double Click On Build Improvments

First, I like the feel of Fallen Enchantress already.  The tutorial only seems to explain things MUCH better and the interface seems a lot better as well.  Just a minor suggestion I thought I would post.  When you select a build improvement, instead of having to select it and then click "BUILD" perhaps you can simply double-click on it as well.  Other than that, nothing to report so far.
