adam12,
Just to expand a little bit on what Anthony said about panels:
1.
a. Since you will need at least several panels for all your codes, put these panels under 1 device and call it IR Codes or something similar. Make sure this device is on the device side (not the macro side) of the remote.
b. Put a small label on each panel with the name of the device.
c. I wouldn't hide these panels since if you need to relearn codes, not hiding the panels allows the scroll arrows to be active.
There are other ways to do it, i.e. you can put the code panels in the device which they control as opposed to all code panels in one device. The "all in one" method works well if you don't intend to use RF, which is not an option with the 2000.
2. There are additional software features in PE4 which make creating layouts easier.
