I'm happy to read that the code works, I will include it in the next official module release.
And thanks for the review on JED, I really appreciate that.
Regarding the option you mention: I really love News Show Pro GK5 and all of the ex Robert Gavick extensions and templates, now part of Joomlart company. (Hi Robert, how are you doing?). A very useful and versatile module with many many pros. The only problem, in my opinion, is that the module has so many options that a lot of unesperienced users are not able to set it properly.
Digi Showcase is born with the idea of semplicity like in the magic wizard "push this button, I'll do the rest for you".
So I'm employing myself to keep the module easy to use.
Besides, I write your request in my todo list of Digi Showcase and I will think about this function for next module versions.
I hope you are satisfied anyway with this module. I'll keep it alive and updated. And, above all, free.
