hi all again!

i was wondering if there is an option to display all datails with logged time of an issue.
i need this for 2 reasons:
1. i need to log to our manager my all activity on paper. so if i worked 5h on some issue i need to print this and leave it to her.
2. i need to print time spent on some issue to sent a copy to a client to make it signed, then we can make a invoice.

it would be great to have a filter on 'issue details report' to select by date, user....

is it possibile? is there any plugin with this functionality?

thanks in advance!
