It would be an added value if knowledge base articles (solutions) are suggested whenever a user starts to create a new incident through the portal. It currently suggests "Services", which might apply in some cases, but it seems suggesting Solutions makes much more sense. At least for us as we are building a fairly comprehensive knowledge base, based on our most frequent tickets and "how to" type helpful hints.
I'm currently doing this with automation and keywords or category/subcategory. But, that requires many custom automations.
