Unable to extend allocation time of a booking


Viewing the BLAB Calendar in Day view, (bookme.name/account/0/calendar) If I try to extend or decrease the time allocation of a booked meeting, it only allows me to extend or decrease it in 30min intervals. Can we please at least make this 15min intervals. for example if I have a 45min meeting booked and I want to extend this to 1hr or decrease it to 30min. Note: there have been no restrictions on the booking padding, interval etc, to not allow this.

Also will the user be informed of this change, or will it just be me.
