I've always found it much easier to read dates quickly when they include words as opposed to numbers only. For example, 10-08-11 on GeeTasks takes me a moment to figure out, especially since different developers use different orders when displaying dates numerically (e.g. is the above example referring to August the 10th, 2011? October the 8th, 2011? November the 8th, 2010? or August 11, 2010?). I would LOVE to have the option of setting my dates so that they read "Tue, Sep 7 '10" under a task, or if they had to be numeric only, then at least having the year show up as four figures, as in YYYY-MM-DD, would be extremely helpful.
If this option is already available and I haven't figured it out yet, please forgive me!
