I am playing with Win500 trial and agree, especially when looking at Trunking Systems (TSYS). Everything is on one tab. The "systems" are in one grid at the top and the talk groups are in another grid on the bottom. You don't have to open multiple windows and dialog boxes to work with objects. It's all in one screen. It has good sorting capabilities and I really like being able to reassign the object ids if needed. This will probably be the one I purchase.I prefer the Win500 software program, it gives you a better viewing of what you have programmed that any other program that I have tried.
