Better UI to make account switching easier

[pjb7687]

I would like to suggest having a better UI for switching accounts easier.

For example, when using the Gmail app, you can easily switch between accounts by just swiping down your avatar icon on the top-right of the screen. It would be great to have a similar thing with the new app.

Currently, you have to touch at least triple times (menu button, switch account, and the account you want to switch), which is a bit annoying.

Thanks for the feedback! This is #1211; I'll close this new issue to consolidate discussion there.
