With Crestron you can have portions of the page be 'sub pages'. So lets say your navigation menu is 100px high and 640 wide. You can create a sub page that size and have it appear anywhere on the 640X480 panel.
This is a nice feature for commonly used items like a clock, navigation menu, volume control etc. Some, maybe most GUI guys make everything a subpage and drive them with programming. Making volume control only appear when a source is actually on. Giving you the ability to hide or show specific controls.
Is this possible with RTI? My RTI skills are limited to the T2-C and i was wondering if the t4 or k4 had these capabilities. I havent been keeping up with 2way news so i am asking those of you who are.
