At work we use Google Apps. I like to assign mails that are important to my work with "todo" and after I did them with "done".
I am pondering a way to do this efficiently and preferably without the usage of a mouse.
Right now I have a label system like:
!Work > Todo > !Work > Todo > Done
Yet here the problem is that I will also see the done-mails when I am looking for some I want to do next.
Also I find myself dragging and dropping labels onto the mails, which I find tiresome. Is there a way to use the keyboard instead?
