Obviously this has been out for a bit now and it works great but we should be able to manage button and box styles in this section as well.
This may be separate feedback but I have noticed that with the button/icon elements, we are not able to save a set theme for them. I find this difficult to use because I have to constantly make the same theme over again or duplicate a previously made element to get the same designs. Having the ability to not only save that theme but have that available in the new section would be incredibly helpful.
