Checklist.com does what I need:
- Multiple checklists for different occasions (I have ones for "Camping", "Hiking", "Going to a wedding", etc.)
- Nested lists ("Clothing to pack", for instance, with socks, shirts, etc. under it)
- Reusable lists (I can uncheck the entire list in one click, then check each thing again)
- Checked items can be hidden at the bottom, leaving only un-checked items visible, if you sort by Status
- Phone app that syncs with web app, so I can check things off on my phone
However, it is slow (checking an item can take seconds to process), and it is buggy (nested lists are not handled correctly depending on the sort, mangling the list permanently), and if you check off every item in a sub-list it automatically checks the parent item, which is not what I would like.
Any alternatives that provide the same functionality without the flaws?
It would be even better if I could categorize list items, like things that appear in both the "Camping" and "Visiting Family" lists, so I could see the union of each list in one place.
I am looking for a "pre-flight checklist", not a To Do list or a habit tracker.
