You should use your browser on your phone if you can't use a computer. Gnik has a lot on his plate, plus it would probably slow the app done adding those features right now. Also you'd be better off posting things like this in General Feedback in the future, but this issue has been brought up a bunch already.
Search general feedback and you'll find a few threads on this, with the answer explained in detail by a mod. If I could remember the exact thread I would post a link, sorry man.
