v1.5.3

Added

• Browser Extension: A Chrome extension that notices when you are watching a YouTube video and turns it into a course in one click, without copying the link across. Nothing is added to YouTube and nothing on the page is read.
• The home screen accepts a video handed over in the address, as /?v=<id>. Arriving signed out, the sign-in screen keeps hold of the video and the course starts once you are through.

Fixed

• Creating a course from a video you already have opens the course you made rather than running the whole generation again to arrive back at it. Then, it shows a relevant toast. The mechanism for this existed but this short-circuiting saves time.
