Would it be possible to have a property copy tool similar to the existing sample tool?
In my mind it would first remember the properties (i.e. tmp, tmp2, temp, life, ctype) of a selected particle quickly, then let you copy the properties of that particle onto another.
I think this would make some fiddly things like PSTN, CRAY, and working with serialisation easier, because we won't have to constantly come back to the PROP tool or make weird single pixel stamps (or is this just me lol).
