Calling all WordPress Widget experts, I am trying to write my own widget, but I am not having luck. I get it to show up in the plugins and activate it, but it doesn't show on the widget list.
I know about Chris Johnson's Tag Cloud Widget, but the cloud doesn't show for one thing, and the other is that I don't want it weighted, I want it shown in alphabetical order. It shows the title and nothing more using his... Okay, I got it to display by changing the display from 1 to 50, but that doesn't do a display all like 0 was supposed to do... Okay, I also got it to display in alpa order so I guess the code below is moot. 
The code appears below the break, with a few comments after the code.

For this plugin, I basically copied the gsearch.php plugin and modified it to my needs

Eventually I'll expand this to actually use the title option...

The $options that I have above was supposed to be so that the user sets it to 0 to get the tags to display in weighted form, the 1 would display the cloud in alphabetical order, with the words being bigger if it needed to be heavy or not.
The title may appear twice, I was trying to test something, but since the control never showed up, I wasn't able to test it. I wanted to see if it appeared the correct way which should be an h3 in my case.
