It would be Nice to be able to manually reject or approve reservations from the reservations list in WordPress admin. Also it should support multiple reject/approve/cancel actions.

For example:

Total seats: 100
Available seats (8:00 – 8:30): 25
Available seats (8:30 – 9:00): 25
Available seats (9:00 – 9:30): 25
Available seats (9:30 – 10:00): 25

possibility of entering number children and adults in one reservation, not just persons. There is one client how wants to know how many children there coming in one reservation

I only need a time for start reservation not for ending.

i want the option that everything is in a 24hour setup is instant am.pm

Ability to add company logo to the registrations and confirmation emails

when admin cancel the booking , Booker must confirm back that they have received the rejection

Allows users to cancel reservations from restaurant web page

Allow to customize fully booked message so I can enter phone number to call

When reservation is created or canceled, notify restaurant stuff via SMS

I want to have a possibility to define a comment for specific date, so that when guest selects that day it will be shown on a reservation page.

Same information should be visible on upcoming reservation list and when new reservation is created, so when manager enters information, he might notify guest about event of the day.

Allow to control where comments fields are shown to clients or not

also a time table per day would be great. so you can see in one look whats coming today

A drop down menu/status bar to show guests have arrived, had order taken, quality check & departure?

combine max seats available by weekday with specific dates

Allow to customize thank you messages

print reservations on a labelprinter like Brother QL-710W

Customization of the buttons and input field (Front-end)
