EasyOrg is the task management tool you need if you like using text-files, but need some more structure to prioritize and schedule your tasks.
If you like Org mode, but find that Emacs makes it a bit difficult to get started or you spend too much time configuring then EasyOrg might be for you.
EasyOrg provides a fullblown editor and powerful Agenda. You can show your tasks in agenda view, Calendar view, List view and Table view. There is also an Org Previewer.
Support for org syntax formatting, tables, lists, scheduling, priorities, effort, custom properties, closing notes, created at and closed timestamps. These are all but a few of the features supported.
Others are internal and external linking, jump between previous visited tasks, embed images, file versioning, org syntax checking and more.
And oh, we forgot to mention search. EasyOrg supports advanced org mode targeted search expressions to find exactly what you need.
