Display the date as well as the time with an option to change the display format dd/mm/yy mm/dd/yyyy etc.
View other channels now/next data without changing the current channel.
Display currently used server/receiving device (a status osd popup) with an option to change the current server (Say you're watching on Server A and it's glitching you could press this option to view the same channel on Server B).
Some more feature requests :)
Hope these are some good ideas :)
