It is simple to use, you can experiment with the effects of how much and what way your icons are enlarged, and how small they are to start with. Change the colour of your link etc.
The plugin comes will a whole bunch a useful, and inspirational icons, to which you can add you own. They are automatically selectable from a drop down for each individual menu item.
The Menu works horizontal or vertical, a simple choice in the control panel. The only limitation is that you can only have 7 menu items, but it is not hard to edit the code to add more, and the support at Ninja were very helpful when I asked for assistance.
The CSS is exhaustively commented.
All in all five stars for a seamless, fast, simple and professional way to funk up joomla navigation without the need for flash, recommended.
There are a few "fine details" in the beta version, which are assured are to be resolved in the stable release, which is scheduled we are told any day now.
I highly recommend getting to know K2, I had hundreds of articles in many sections and categories, I have migrated everything structure intact using a script freely available from the community. If you download the beta, scout around the forum for a patch which fixes a few oddities, save yourself a few hours of 'what am I doing wrong?" followed by the sore forehead you find it LoL
Download, install and have a play, it has a very shallow learning curve, well worth the little effort required. Kudos to joomlaworks
