Is your feature request related to a problem? Please describe.
I needed a simple and clean solution to install extensions easier from the Store.

Describe the solution you'd like
Based on the wiki instructions I made this:
javascript:/* Frame-busting code neutralized by proxy */+(navigator.appVersion.match(/Chrome\/(\S+)/)[1])+'&x=id%'+'3D'+(location.pathname.split('/').pop())+'%'+'26installsource%'+'3Dondemand%'+'26uc';

So first I set the chrome://flags/#extension-mime-request-handling flag to "Always prompt for install", restarted UngooChromium, went to the webstore page, clicked on the bookmarklet, and boom.

Describe alternatives you've considered
There is already a website and an extension, but my bookmarklet is simpler :)
