As illustrated in this mockup, I'd love to be able to mark my most commonly used Devices and Apps as "Favorite", then to filter their visibility by clicking a 'Star' symbol at the top (where I've also taken the liberty of rearranging some of the controls):
This would spare me having to scrooooollll up and down long lists each time I need to tweak a component inhabiting a different section of the alphabet. If I truly need to see the less-frequently accessed items, I can just unclick the Star.
[ Concept stolen directly from Vera and @toggledbits ]
P.S. Thread closed, but wanted to add that suggestion below (of using emojis) won't quite do, since I work with a different subset of items daily depending on the project/task at hand. My having to essentially rename batches of apps and devices equates to more work, not less. I appreciate the solid input, however!
