When a player is concentrating on a spell, they often want to see which other spells they can cast without breaking concentration. The current single-click concentration filter, which shows only concentration spells, does exactly the opposite of this. It's generally not helpful to to see a list of spells which are mutually exclusive with each other.
This capability has been requested a few times in the Character Sheet Revamp Feedback mega-thread, but that's almost 200 pages of varying feedback, so here's some cross-linking: here, here, here, here, here, here, here, here.
A related idea (which has also been mentioned previously) is the more generalized capability to filter out spells whose components a player can't access. This comes up fairly often in normal play:
I need to be extremely stealthy, so I want to see spells that I can cast without verbal components.
I am under the effect of Silence, so I want to see spells that I can cast without verbal components.
I am holding two weapons or a weapon and a shield, so I want to see spells that I can cast without material/somatic components.
I am using my hands to climb/grapple/move something, so I want to see spells that I can cast without material/somatic components.
The way I see it, this idea just extends the idea of filtering out things you can't (or don't want to) do from "concentration" to "any spell aspect".

This sure has been requested for years now, many many times. Wondering when they’ll spend the ten minutes it would take to code this.
