In what context is the slider available?
You need 1 license per site.
Is it good of anything? http://templatetoaster.com/ Does it worth 149$?
If their homepage and examples are anything to go by, it doesn’t look good.
Can somebody make a theme with this software and have it approved here?
No, themes and templates need to be hand coded so that the code is as perfect as possible, if you can’t code by hand then you can’t fix bugs and shouldn’t be releasing themes.
WPEngine or ASmallOrange
@matthewcoxy that’s a lovely response, kudos
Use the theme customiser and it’s new panel options, great for decluttering
