I am often working with hundreds of cards across Main/Sideboard/Considering, and from the deck view will ask, “What are all the cards here that mention _? Or have p>4? Which boards are they in? What do they all look like together?”
Basically, just let me use scryfall search/filtering on the deck page so it only shows cards that match that search.

Unless I’m misunderstanding what you’re looking for, you can already do this using the highlighter tool.
Looool nice. I was kinda hoping someone would say this already exists. Thank you very much :) I’ll try it out but it looks like it will be great.
