Thanks for the feedback! Delighted to hear it's working well for you. Currently, HoneyDo supports one list to keep the initial release simple, but multiple lists are on the roadmap.
Oh, and I almost forgot to mention a feature "Pic to Pick". It's pretty cool; you take a photo of a dish or your fridge's contents, and the app (in this case powered by GPT-4's vision model), identifies the items and suggests them for your list. In my tests it works great.
Well, the key is to find something new, exciting but not easy to achieve. For me it's PPL (private pilot license). This is very technical (a lot of IT folks love it) and has a steep learning curve. After starting doing this you'll feel much better again, because you'll have an exciting goal to achieve.
