Update installable app, new video

Work is busy, so I only updated some branding, logo, etc. I also made another YouTube update video and have worked out most of the script for my next video discussing different tech.

As part of my marketing plan, I am building in public and using YouTube videos to do so. The next video will focus on frontend tech and hopefully be more SEO friendly. Since I have a handful of videos about my app thus far, I'm hoping to start gaining traffic to it by reaching a broader, tech and product focused audience with new videos, and funnel them to the channel and app.
