How to hide marked entries
If you have Job Sheet entries that you would like to not be shown, you can mark them and then click the Hide marked entries checkbox. If you check entries while this checkbox is checked, they will not disappear immediately. The next time you view the Job Sheet for the project/matter those entries belong to they will no longer be shown. You can force them to disappear without changing the project you're viewing by toggling the checkbox.

To make marked entries reappear, uncheck the checkbox.

The Hide marked entries does not override your settings in TimeCache Preferences for hiding invoiced entries.
