Yes, the departure hall is inadequate at some times of day; the downside of EZY bringing forward their 4th based aircraft by 12 months and prior to the terminal extension being completed.
The new arrivals hall is now in use and perhaps you would like to give your impressions on your return flight. I don't think the new departure hall and additional gates will open before the end of the year and it's a pity if passengers are somewhat put off by the current departure hall's limitations.
