I am mostly referring to show or movie creators answering questions in ways that might effect the lore. They don’t have to be plot holes, super significant, or still held to be canon.
For example maybe it was a small detail they elaborated on or they answered a long running question.
I was originally going to give the example of why characters in Star Wars don’t toggle their light sabers on and off during combat but it seems like the explanation I was more of a fan theory from what I can tell.
The question can also apply to video games if you have an answer with one of them.
Probably energy efficiency reasons.
When you’re beaming in or out from the transporter room, that’s only one “hop”. When you beam from elsewhere to elsewhere (bypassing the transporter room; aka a “site to site transport”), you’re actually beaming to the transporter room and then back to your destination, so it’s two hops; you just don’t materialize between the first and second hops.
