(come on you guys, anything this repetitive is off topic on HN. we want curious conversation here...)
$50/yr for all that is a steal. They don't charge you per-domain or have any funky tiered pricing for the stuff that matters.

I've found that code reviews are the best way to mentor and transfer knowledge. And it goes both ways: you review their code, they review your code. When I'm explicitly training someone, I get them to review my code and I occasionally throw in some minor curveballs that I expect them to pick up on in the first few rounds (e.g. obviously incorrect conditionals, some convoluted loop, leaky interfaces, etc.) If they stamp the PR without picking up on those items, I highlight it using a "do you think this is correct/is there a better way for us to do this" line of questioning. 5-10 or so PRs later, they become the first to spot those issues :-)
I personally find the search summaries helpful more often than not, and it works nicely in products like Google Sheet.
There is an extension posted here a few days ago that you could try [0], but I think that's only for search summary.
