Thanks for this great plugin!
I'd like to suggest for future versions adding the ability to create categories, and to sort/display data via categories via the Q.C. widget(s).
Also, I'd like the ability to be able to create & show more than one widget (which is not possible currently -we can only create/use one widget). I tried to get around this limitation by using the "Ad Codes Widget", which can display shortcodes, and then sorting the data by using Tags, but no luck - the Quotes Collection widget showed data which was tagged with a different tag to that which I'd specified in the QC widget settings/parameters (...so it's not obeying the Tag parameters that I'd set within it), and the Ad Codes widget worked, but the text was centered.... ah well, I'll just have to settle for one category it seems.
It would also be good to be able to sort Quotes via Tags or Categories in the back-end.
But I love this plugin, and would highly recommend it.
