What I really would like is a recommendation engine for me personally. Basically: This is what you could cook today (you haven't cooked this for a long time, but like it or so).
Then, when I do meal planning (usually in the weekend, depends on when we have a slot for grocery delivery) we (as a family) look through the table of contents of our family recipe book/binder and we usually eat (per week) 2 to 3 recipes from there, 1 or 2 from the 'we should try these' sources (printed recipes we come across, our newspaper has recipes daily, pinterest boards, youtube videos, ...) and 1 or 2 nights we have leftovers or takeout.
This planning ties in with an offline-first grocery shopping/meal planning system that revolves around a cork board with laundry pegs to hold that weeks planning, which my children made/decorated when they were little.
I enjoyed it a lot, but eventually my life got too busy to cook that often and I was growing slightly tired of the recipes, plus they got acquired so I don't know what their future holds. But maybe you'd find them valuable?
