Tasque
Even though it is a simple ToDo list manager, Tasque is extremely useful and versatile that everyone will love to use it.
When you first use Tasque, you might be surprised to find that there
is no menu bar or any other miscellaneous features. In fact, there is
almost nothing in the whole application window except for a dropdown
box (to access the categories) and an input field for you to enter your
tasks. That’s it, nothing more.
One of the best thing about Tasque is its ability to synchronize
with Evolution and Remember the Milk. It is also supported by the Avant
Window Navigator (AWN) dock so that you can access your ToDo list
directly and quickly from the dock.
In Debian-based distro, you can install Tasque via the ‘tasque‘ package in the repositories.
