no answer, what a waste of time this block is.

I hope you've had a great Christmas.

I'm a bit disappointed by this message as I endeavor to provide top notch support for all our blocks. I receive excellent feedback like the following from C5 customers regularly:

But please also be realistic - you ask a complex questions a couple days before Christmas when many people are travelling to see family or on holidays, requesting support for a free add-on, and expect an answer within 24 hours before complaining about the lack of an answer. I'd suggest you think twice about that.

But I'm always bending over backwards for customers, and will still answer your question.

That particular version of Cu3er does allow you to change the position of the arrows, as well as change opacity and button shapes/icons.

Here's the link to the original developer's doco which explains:

Simply add the "X" value in the appropriate area of the controller.php file (do a search for "<settings>"). I don't have the source code with me as I'm away from my computer of the Xmas break. But this should point you in the right direction.

Have a merry Christmas and Happy New Year.
