Would like ability to make default "Before End" notification time a percentage of the reservation time instead of just a fixed value
We receive user complaints that they don't get enough notice that their reservations are expiring and they lose them before they can request an extension. There is the option to modify the "Before End" notification time for a reservation but they often don't do that and just get the default value.
While the appropriate default "Before End" notification time for a reservation that lasts a few hours might be 15 minutes, that little notice usually isn't at all helpful for a reservation that lasts days or weeks. Likewise, a notification time of two days might be appropriate for a reservation that lasts a few weeks but it obviously doesn't work for a four hour reservation.
I think it would be much better for the default "Before End" notification time to be specified as a percentage of the reservation length (or remaining time, in the case of a reservation extension.) For example, a Before End notification time of 15% would provide an 18 minute notice on a two hour reservation or a 3024 minute (50:24:00) notice on a two week reservation.
