  3. Lovely redesign that addresses usability complaints I had with the old version. In fact I built my own search tool for Google Fonts a few months back because of these issues: http://fontcdn.org Some of my critiques of the old version: http://thomaspark.co/2015/08/a-better-way-to-search-google-f...

  17. I made a browser extension called No Scary Parts that skips traumatic scenes on Disney+ while trying to hold together a cohesive plot. Mainly for young kids who enjoy the music and other scenes, but aren't ready for the full story yet. https://thomaspark.co/projects/no-scary-parts/ Fantasia was easy. Managed to do The Lion King. Haven't been able to pull off Bambi yet...

  29. Yes, they did eventually. If I'm understanding correctly, the original design used a simple funnel shape with 45 degree sides (suitable for the resource-limited systems of the day), and when they eventually re-implemented it they used a funnel defined by the left hand corners of the submenu, as per the Amazon design.
