Rather than a freetext field, I'd love it if one could multi-select specific locations as can-work-from. Like, if the job is remote to the whole US, be able to select that item from a location hierarchy. Bonus: ability to layer on negative things like "Anywhere in the US except [these states]". And then, a filtering feature so seekers can say "I'm at location X, please show me everything I can apply to without moving (on-site here plus remote jobs I'm eligible for here)."
