Hi @Terence996,
Thanks for your in-depth feature request!
So in summary, you’d like the ‘Keyword’ filter (your example is the lowercase cat) which currently searches for matches in the card name and content to also search for matches within a cards’ tags?
We could definitely do this. However with the arrival of custom collections soon, we will also add a way for you to create complex filters using AND and OR operators. So you could create a filter which searches for “the keyword cat or the tag cat”. This is more explicit, and might make more sense would this be too long-handed for you?
We are also going to overhaul the ‘Search’ (previously called the Command Prompt) to also look for matches within the card content, and since it’s a fuzzy search it would make sense to look for matches in the tags of cards as well. Would that be useful for you?
