Feature requests:
1.) When I add a task, sometimes I'd like to add a really detailed description (or any description for that matter) (i.e. a project spec) and I'd like the ability to do that. The ability to bold, italicize, change font size and format, etc, would be helpful in descriptions.
2.) Attachments. I want to be able to attach files to my tasks.
3.) Keep the above features out of the way. Most of the time I won't need them, but when I do, I really need them.
EDIT: 4.) Just realized that the projects aren't hierarchical. I expected them to be, and it doesn't allow me to be super organized for more complex projects/tasks. An example of this might be Work>Websites>ClientA and another might be Life>Exercise or Life>Clean-Up.
If I think of more, I'll let you know. Nice job so far.
