To make the long story short, here now is ssButton class with 10 themes and 6 colors to choose from. I also changed some old themes with new looks as well. Further, I added in the sample demo portion of the codes shown in editboxes just so you can follow how to use the class easily. I won't show much images anymore here, anyway when you download the library you can play with it and see those yourself.
For comparison, shown below are ssSwitch with Theme 18 and native VFP checkbox. Enjoy!
