Cancelled payment schedules are still shown on main ZapPlanner page

[btcschellingpt]

After cancelling a previously created schedule, the schedule is still shown on the main ZapPlanner page.

This creates confusion as there is no distinguishing between active and inactive schedules.
Pressing the "View" link takes you to a new 404 page - so schedule clearly gone - good but slightly messy.
Clicking the schedule itself takes you to the meta-data for the schedule where there is a "Delete" icon.

I can see the value in retaining the detail of the cancelled schedule as it lists the payments made under the schedule. That could be useful for auditing, checking/validation purposes .. certainly for general record keeping.

Possible approaches:

1. Delete the entry from the list when the schedule is cancelled - clean but lose access to payment data
2. Add a second list as a RHS colum "Cancelled Schedules" - Active schedules on the left, Cancelled on the right
3. Keep a single list but differentiate with colour/shading/intensity but Cancelled has no
