fabacab/fetlife-aslsearch ? reverse-engineered prompt

Build me a browser user script for FetLife that adds an extra search panel to the site so I can find profiles by age, sex or gender, location, sexual role, orientation, bio text, fetishes, and what people say they are looking for.

I want it to feel like a normal part of the FetLife page, with a simple checkbox or tab near search that opens the custom search area, short help tips for the fields, and a clear results table with profile photos, names, and useful details. It should let me expand rows for more info, filter the current batch of results, page through more results, and start over with a reset button. If possible, let me send a message to someone directly from the results list too.

Please make it work as a Greasemonkey or Tampermonkey style script, and if you need current details for how FetLife pages work, look them up online first.
