> Hey Vadtec,
> This is an excellent extension... I am in need of almost the same
> extension, but mine should just show the progress bar, not the
> outstanding/completed lists of tasks.The only data that should be sent
> to the progress bar should be an percentage, or a value, example
> 250/1000 which is 25%.
> I want to use the extension to show how many articles I received on my
> website, compared to the target for the whole year.
> Do you think one can change this extension to do this?
> Thank you.
