andrew Thanks for that!
I’m beginning to believe that no amount of pure explanation or ingenious metaphor can really do the job of making Filters an accessible tool – not by itself. Adding things to Legend that “support” the way filters work – such as these “partial expansions” may be a key part of the solution.
I don’t love the half-turned ‘collapser’ idea. Easy to miss and not very specific. But better than nothing.
You know how the words that match a Find are highlighted in yellow to help spot them? I wonder if a similar visualization could work with Filters to indicate the exact items which are matching a filter. Would also be just plain useful for troubleshooting, too. Default it on, but able to toggle off. Could be done many ways – ideally something elegant enough that it could be left on while working and not be in the way. The right margin seems to have enough space for this.
