TL;DR of the suggestion: Let users create lenses with custom pinned/promoted/blocked domains.
I'd like to suggest as a new feature for Kagi "super lenses" or portals, with additional features from current lenses. The most important feature addition would be to let the lens creator make a list of domain rankings that are connected to that particular lens. This would open up for users to make lenses that can become incredibly useful for other people and even help Kagi get more customers.
For example, a person could make a lens for scuba diving with domains up ranked, down ranked or pinned as they relate to scuba diving and nothing else. Another person could make a lens for lawyers in her specific region, pinning domains with laws in that region and down ranking some domains that deal with law in a different region, if they keep showing up. Another person could make a lens for open source software, and make sure that Thunderbird is pinned when somebody searches for e-mail with that lens. A music lens would show a certain result for the term "Scorpions", while a biology lens would show another.
Now why would anybody care for this, except the lens creator? I suggest that these "super lenses" should only be available to be made as public lenses (just an idea). I also suggest that the Kagi team could copy/fork lenses that are of outstanding quality or usefulness, giving them official links for easier access, such as for example birdwatching.kagi.com or travel-nz.kagi.com or architecture.kagi.com or frenchcuisine.kagi.com, to use some made up examples.
If you really want to go nuts, you could also let the super lens creator specify an AI system prompt, which would be used only in connection to that lens.
Another use is for enterprise, where the organisation might want to have a site ranking especially for their employees, for schools, and so on.
The first super lens to create would of course be a lens holding the aggregated community ranking list, as suggested in this thread: https://kagifeedback.org/d/4502-opt-in-collaborative-shared-result-ranking
