I Think you can put this into single local HTML file and instead of polluting your bookmarks with thousands items make just single keyword bookmark pointing to the HTML and let it handle all the functionality in embedded JavaScript. The only difference would be one extra space needed for invocation, i.e. instead of `!github test` you'd need to type `! github test`. I tried this about ten years ago and it seemed to work.

'>', '#' or '!' for it # try it. you should see a list of defined 'bookmarks' (testing only) # extend, tweak. # remember that you must use space after the main Keyword: "> command argument1 argument2" */
