Hey,
a few days ago i was looking for simple automated time tracking tool. my idea was that it will just record the title of the active window every 10 seconds. later i see all my records in one list where i can search and assign (via drag and drop) each "application using" to an activity (e.g. "Work on Project X"). at the end i can create a report for a specific time period, so i can see that last month i worked 6 hours on project x, 20 hours on project y, 3000000 hours checking mails and reading feeds :).
step 2 would be that all the usings are assigned automaticly to activities based on window title filters ("Google Mail*Firefox" => Reading Mail, "Project X*Eclipse" => Project X....).
i found a tool called slife, which is almost wanted. but its not open source and only available for windows and mac.
so im thinking about doing it myself for fun in python. i attached some mock screenshots.
i would like to hear from you guys, what you think about this, would it be useful for you?
