I am already aware that Dynamic Checklists mod exists, and I have tried it out (had to download the updated mod from the pull request as I am using SMAPI 2). However, the mod does not do what I wish it did. What I want is a checklist system that allows me to create a reasonable amount of checklist items that I can manually check off myself when they are completed. I do this currently with a notebook, but it would be nice not to waste paper doing it and to be able to do it within the game. Heck, lets take this one step further by allowing you to select a "goal" date by which you want to have said task done - this would be for tasks that cannot be done within one day, such as "Get 7 hearts with Lewis" or something, though it might be hard to estimate completion time. Nested items would be nice as well, allowing the creation of a more complex checklist like "Complete some bundle" with a sub-checklist of items needed for said bundle. It's astonishing to me that I haven't found a mod that does this, I can't possibly be the only one who wants something like this.
