Although I had a requirement that wasn't addressed, Fiona told me it could be easily done through a minor change to the CSS code. Not being a CSS pro, I was a little concerned about being able to handle the change. After installing the module, it took less than five minutes to make the changes based on the instructions and sample code from the developer. The CSS is very clean and easy to understand.
The basic module does what it is advertised to do - and more. It's a snap to install and configure. Minor modifications, beyond the flexible options, are very simple to undertake.
Support, though not generally needed, is quick; the answers easy to understand.
I wish I had evaluated this module before looking at some others. I could have saved myself a lot of time. I highly recommend Mod Panel Slider. It is well worth the small fee.
Being fairly new to Joomla, I had some minor problems with the initial setup. When I contacted Jonathan, the author, he was very helpful and got me up a running. Since then, he has released a new version of the enhancement. During the testing, he was very responsive to suggestions and quick to resolve any problems. All in all, this is a very useful, workable enhancement.
