I find it a bit cumbersome to change themes in Hyper. Is there a better way than

• first open .hyper.js,
• find plugins: and then possibly comment out your old theme and then
• write the name of the new theme you want that you found somewhere on the web?

It would be nice to have some sort of shortcut and possibly have a option under view that open a grafical theme picker that resembled https://hyper.is/themes and when you clicked a theme it automatically changed in .hyper.js and the theme was updated. I believe this would made the transition to Hyper easier for most people!

Start by reviewing the existing .hyper.js theme configuration and the Hyper themes page referenced in the issue. Determine how a View-menu entry or shortcut could expose theme selection and update the configuration. Done means users can choose a theme through a graphical picker and see the change applied automatically.
