I read (somewhere in the forums) that when I modify my Sliding Panel style (color, backgrounds, etc.), I should save those styles in a directory separate from where Sliding Panels stores its styles -- so that Sliding Panels does not overwrite the changes I made.
I believe I have done that successfully, but is it possible for my own version of Sliding Panels to show up as an option in the Design List in the Properties when I use it in designing other websites?

Hello David,
Unfortunately it is not possible to show your version of Sliding Panels design as an option in the Design List in the Properties .
