Seyal

It installs Seyal in your own programs folder and puts it on the Desktop. Or paste this in PowerShell:

• Edit task (was "Change the task") has everything New task has, the checklist too
• Who checks it: choose anyone who is not doing the task
• Two or more people: "Everyone does their part" or "Any one of them can do it"
• Checklist: common, or items for each person; rename, move, remove items later
• Shared tasks show "Put on hold" and "I can't do this" together
• Phone: buttons always above the phone's own bar; the update box scrolls; tabs fit big text
• Windows: Seyal lives in one fixed place with a Desktop shortcut, and updates install there by themselves
