In the video that shows the stolen tools in the warehouse, there are hardly any Ryobi tools (HomeDepot's cheap tool brand). This is in stark contrast to many of the recent woodworking videos on Youtube that feature craftspeople using Ryobi tools (without explicitly mentioning an HD sponsorship). The thieves know a good tool, and HD is trying to fool the rest of us that their Ryobi tools are any good.
CueCam Presenter solves this quite elegantly: You can prepare a script with a card for each window you want to share. Then you can just select the card during the presentation and it will share just that window.
I also have a single large screen. So I put the CueCam window on the right, top to bottom. And the windows I want to share in the bottom left quadrant. There I can make them smaller, with the correct aspect ratio, so that participants with smaller screens can see all the detail they need.
That leaves the top left quadrant for my meeting window where I can see the meeting participants.
I'm also experimenting with the two companion apps: Shoot to use my iPhone camera and control zoom from CCP; and Video Pencil to draw on my video.
Plus one for structurizr. Its model driven approach makes it a lot easier to keep the diagrams consistent with the code: You describe the architecture, and structurizr renders the diagrams.
I looked at the avisi stucturizr-site-generatr, however, decided to render the docs via structurizr-lite. It provides better interactivity for C4 model diagrams, e.g., drilling down into diagrams and tooltips. I found the ADR integration in structurizr-lite sufficient.
I've been using https://structurizr.com/ to automatically generate C4 diagrams from a model (rather than drawing them by hand). It works well with the approach for written documentation as proposed in https://arc42.org/. It's very easy to embed a C4 diagram into a markdown document.
The result is a set of documents and diagrams under version control that can be rendered using the structurizr documentation server (for interactive diagrams and indexed search).
I also use https://d2lang.com/ for declarative diagrams in addition to C4, e.g., sequence diagrams and https://adr.github.io/ for architectural decision records. These are also well integrated into structurizr.
At ContentGems.com we aspire to offer some of the features you're looking for. We fetch a ton of feeds each day, index them, and let you filter the items based on a powerful query api (Lucene). So in addition to reading your own feeds, you can also extract interesting content from other feeds and discover new feeds. It also deduplicates articles (on a sliding scale of similarity). We are in the process of building out the feed reader component (which is trivial compared to what we're already doing with search). An interesting twist on feed readers is that CG treats your Twitter home timeline like an RSS feed, indexing all shared articles and including them in the Firehose of feeds.
