Hi degarrin,
At work, so I have to be brief. Thanks for your suggestions. Some of these suggestions are implemented already. For example, you can add video and pictures right in the text editor. Pictures and video, however, will be stripped from the tooltip as they break the pure css tool-tip solution.
The audio pronunciation is a good idea, and something i have wanted to implement. Something I have to figure out.
You can currently assign a category to a menu item. I need to clean up the implementation of that though, and plan to make it more SEO friendly.
I am not sure I will ever make it 2.5 compatible. Maybe someday. Currently I am starting a new semester of college at a new University, so the backwards compatibility with 2.5 is on the back-list..
Switching on and off the tooltip for specific categories is a good idea, and something that could easily be implemented. I may take a look at that next.
Thanks for your ideas!
