All true. This is version 1.0, far from perfect. Good advice, will fix all that soon.

Re the second part: search is by condition, so all specialists ranked relate to that condition. Each condition may be managed by multiple specialties, which is why the Specialties filter is extremely important. For example, you may already have a pulmonologist, but you need an oncologist or a surgeon. You can filter search results to only retain oncologists.

Not sure what you mean "specialist field directly". We will allow search by specialty, meaning that you can select "cardiology" or "oncology". That search won't be condition-specific. It'll rank e.g. oncologists across all cancers.
