it's been about two months since you submitted this and things around Ki have been improving, for example it can do site: searches now. But I think in general a lot of the feedback you submitted should have improved, could you maybe re-evaluate your findings?
About your first screenshot, I'm not sure if that's the best use of Ki, in the sense that: it's better to ask it a question I think. But sure.

define additional workflows via APIs
This will probably be done via MCP's which is in the works
Deep Research mode is also coming.
Also it tries to be smarter when searching now, while it can't yet do more advanced things than a site: search, it does seem smarter than it used to be. for example if you ask for info about OpenStreetMap tagging, it'll likely to a site:wiki.openstreetmap.org search.
But yeah, won't comment on everything you mentioned in your feedback because I think a lot of it is already addresses actually. Feel free to try it out again and let us know
