I'd like to have the ability to view the available times in a grid format. Currently there is one list and it means that users have to scroll to find the time they'd like.
It would be a hige UX improvement leading to reduced friction and improved usability especially for mobile devices.
A toggle swich in the booking itself or globally per account would be a massive help.
Display time slots as a list or grid 2 or 3 per row.
Maybe you could have a custom CSS option that can be applied to allow the users of the TidyCal booking system to control how it looks for their bespoke usage case.?
