I want a simple web application that helps users manage ToDo's (tasks). A snapshot of requirements is as:
Users register and login (very simple registration form with 2-3 fields only)
Users see a list of dates (01, 02, 03) as columns of a table...
In next row of a particular date, users writes a task (meeting with John) and the task is shown there. So, it is just a list of tasks for all days; of course users can leave any dates blank
For any task, user can select a color-coded flag, to assign priority
Users should be able to drag tasks from one column to another (to change dates).
I have told about 80% of functionality, rest will be discussed with shortlisted providers.
I will prefer OpenSource technologies (CMS/frameworks); please suggest and the reason why you suggest it (for example, why WordPress, why Smarty, why Drupal, why ABC....
I will provide the PSDs, and I will test the application myself for functionality.
Thank you.
