I have a 'feature request', can we manage which sites are being used by some categories in the frontend? For example, if I build a list of websites and out them under "coding", then I'd like to use those to answer my programming questions. Meanwhile, I'd like to add an "art" category for museum's homepages so that I can ask which year was XYZ painting from. And so on. The current implementation looks like the inter-operability with searing is more static... IDK if searxng has an API to switch those filters or if they can be managed already through 'profiles'.. that kind of thing..
