This plugin was extremely simple to install, set up, and insert into posts. Did exactly what I wanted, with no hassle - I highly recommend it.
The interface is great - although It would be prettier if the slideshow images weren't listed in the narrow side-column, but that's a minor thing. In terms of functionality it's all there and worked just as I needed.
In terms of tweaking exact text placement and display of image titles during the slideshow, not all the attributes I wanted to change were available via CSS, but what we did get looks very good regardless.
None of the updates I've ever installed (plugin, theme, wordpress) broke anything, which is encouraging.
