Add a nice way to switch between open and closed issues/prs

[nikitavoloboev]

Currently you have to edit the actual search field and swap open with closed. That takes too much time.

Ideally the app provides a nice toggle between open and closed views of issues and prs. Perhaps by tapping on issues/prs field again would switch between two views. So if in issues, user taps issues tab on top, it would switch to closed issues view. Tap again, go to open.

I would love to implement this. Any where I can look to dig into solving this?
