Sorry... (I couldn't help it!)

That said, I'm looking at u/Modi57's very helpful link above. Looks like there's some really interesting beginner project ideas.

For my first more-involved project, I'm thinking of making a menu system, that allows me to select a category, and then it calls Chrome to open webpages on that topic, that I usually visit.

So for example, I like to follow SpaceX news, so if I select "SpaceX" on the menu, then it would open the forums, subreddits, and aerospace engineering news sites I like to check once in a while.

Or... if I want the weather report, I select "Weather" and it opens not only the forcast page, but also loads a couple of weather radar pages.

Or... if I want a traffic report, I would select "Traffic" and then there would be a submenu allowing me to select which part of the city... and then it would open up the traffic camera pages for roadways and highways for that region of the city...

etc...

Would actually save me a lot of clicking time, and opening multiple pages manually.

And of course once the basic version of that is done, then to practice my C skills further, I could gradually upgrade it, and maybe add simple 1980's style graphics, then add animations to the menu selections, etc...
