Yes, Yes, Yes - how can i see the detail for each instructor.  Currently an instructor may only teach half an event not the whole time.  we can edit this time but not see the detail only the summary total.  Can someone create this simple change?  Please please please

Failing adding court closures - can we at least get a court closure report - can't see anyway this is available without trawling through each day on the scheduler

Applying Credits to revenue categories is essential for correct Accounts receivable management.  If in July I charge for an event to an "Event" revenue category and then in August I offer a credit for some reason I want to be be able to apply manual credit (for an unpaid item) or a partial refund (for a paid item) but in both cases have a transaction date in August with a revenue category of the "Event"  This will make my accounts receivable correct for July no matter when I run it as the credit transaction will be in August and for the correct revenue category. 

It would also be amazing if the email system would allow addition of "mail merge" style fields.  So you could write to Dear Tim instead of Dear member,
