I agree. Local variables are definitely better than property nodes for changing values of the objects in the front panel. Although, excessive use of LVs can lead to max memory usage and slow down the program. The only problem I see is: what if one wants to change properties other than the value of the FP objects, say the background color of a temperature control? I've found out that the best thing to do is to avoid using numerous property nodes (multi-channel read)in case and sequence structures which are embedded inside FOR or While loops.
