Related to writing scripts on Mac OS, I highly recommend rumps (https://rumps.readthedocs.io) to show anything you want in your status bar.
For example, I have one script that uses rumps to show how many outdated homebrew packages I have (and also as a convenient shortcut to update those packages in the dropdown menu). I also have a second script that uses it to show a counter for open pull requests that I need to review (with links to individual PRs in the dropdown menu). It's great!
I basically do all my local management from there, no need to run scripts manually, no need to click around in Finder manually, I even added a command to quickly copy my email, simply because it is so low friction to do it.
