It would be great if HowDoable users could create their own categories (with arbitrary names), and file How-Tos under them. Ideally, those categories could then also be linked to, and all public How-Tos in a category would be shown in a nice list.

The use case I'm currently thinking of, is creating a couple of How-Tos for a Hosting customer. For example "How-To restore a backup" and "How-To update the system". I'd like to create those How-Tos, and then give the link to them. The category could be named after the customer.

Currently public profile URLs use some internal ID in it like http://www.howdoable.com/p/2/ - use account name instead to make them more user friendly (and search engine friendly too).

I'd like to be able to print a checklist to take with me on a trip or event.

Allow printing howtos without starting them as well as todo-lists with current status and variables.

It'd be great if some tasks had dates associated with them and it was possible to get notified on these dates.

These dates can also be based on main date, e.g. "two days before main event" or something like that

I would like to see history of my completed todo lists.
like timestamps for each task done.

allow to step a particular step to be required before any following task can be completed
