I agree with these things. I forgot about sortable and filterable tables, but it is correct it should be having. (I would also like the ability to override the browser's default styles without overriding those of the web page, in addition to the ability to override the styles specified in the web page.) If the browser uses SQLite databases for anything (such as bookmarks and cookies), let the user enter SQL commands to sort/filter HTML tables (and export them too, since the commands are entered by the user rather than the web page author, they are privileged). And, yes, it would reduce complexity in the ways you specified, in addition to improving efficiency and allowing the user more control, and these are good things to have. Maybe someone will make a web browser program that can do these kind of things.
