May be overkill, but may become necessary. Many locales are going to require limitations on appointment booking...
...within salons such as # of guests at a time, time between appts, number of staff working concurrently. There may be some slight adjustments to match maker that would greatly benefit those urban-salons that would be subject to such regulations.
Use case; limited amount of concurrent clients.
Option to set concurrent clients at a limit, disallowing manual and client self booking beyond that set limit.
Use case; limited amount of concurrent staff.
This would likely be manually controlled by salons.
Use case; time constraint requirements on time between clients for sanitation protocols.
Option to add a buffer to all appts (pre or post appt) instead of to individual services. Added option would be able to be changed on the fly for all appts without having to correct every service's individual timings. Would also be beneficial to the business if in notifications to clients that it showed on their booking confirmations that a "sanitation time" or such was alotted before and after the appt.
