Make /weblinks page collapsible.

Hello. First of all let me tell you that I find your plugin wonderful. It's all I wanted for links to appear.
I did like the idea though, that the links should appear categorized, and, even better, with the collapsible fields that appeared on the admin section.
So .... I took the opportunity to play a little bit with the module (I'm NOT an expert on php coding, just trying to find my way in it). I managed to do what I wanted to do, but I think it still needs some coding/fixing. Nevertheless, I found it a good opportunity to share it with you.
The module has alternations on lines: 768, 771, 777, 783-830 (I'm mentioning this for you to be able to trace it down).
Unfortunately I don't have module live to see a demo, since I'm still setting it up on my test server.

Again, thanks!
