- remember the settings the window was used last time or allow to set a default configuration (which rate to show and so on).
- keep the settings as long as the window is used. Right now, every date change resets all selections, forcing me to reselect the rate type and the room type every 3 seconds.
- if I change the arrival date, the message "invalid range" is not really helpful. The window should instead change the departure setting accordingly. Means if the customer inquired a 3 night stay, changing the arrival date should change the departure date for a 3 night stay.
- an option to see the rates day by day, not only the average rate, would be great too.
