I am using this plugin for an online language school as well. I agree with chantalf about the booking feature. Please also include a log feature, so that the user can see in their profiles all “used hours”. I would be interested in purchasing the Premium Version if it includes both functionalities.
It would be great if, in the log of used hours, you would include an option where ADMIN could include a certificate of the “used hour” and that the USER could download it from the log in their profile.
I would like to request a notification feature as well, that could notify the USER (via a popup on the website, and/or via email) when the remaining balance of hours is low (when they have “used” 90% of their hours).
Thank you, @wpnetworkit This is the only plugin that is near to meet the requirements for my project-
