Not enough Icons with themes

It seems each Theme has a different number of icons in the IP.  While some have over 100 -- I was very disappointed when ONLY 53 icons included in the Sunny Day Theme.  Not enough to even take care of most of the important file icons.  Is it possible that a FULL preview of the icons that come with each Theme be shown in the screenshots OR the number of icons be mentioned in the description of the Theme?  I would NOT have purchased this Theme had I know it only come with 53 icons.
