Have more than 20 bookmarks, and make lists?
Allow users to have more than 20 bookmarks and allow them to make bookmark lists similar to what the Wikipedia Phone App has perhaps?
I do not know why there is a limit or if there is another option other than bookmarks to save articles. Maybe I am unaware of it.
I would also like to thank you for your extension and website, it is handy and way more aesthetically pleasing too, and makes for a better reading experience :)
