168	poor detection of lowest unused model ID number	Elaine Meng	Tom Goddard	"If you close everything, model ID numbers start over at 1, but otherwise, there is poor detection of lowest unused number as additional models are opened.

Currently if you don't close everything, it seems to pick the lowest number not yet used in the session even if there are many lower numbers available (i.e. models had been closed).  

I favor the lowest-available approach as used in Chimera1.  Tom G suggests an alternative: add 1 to the highest number currently in use. Either would be an improvement over current behavior.

I didn't know how to classify or assign this; feel free to change it."	defect	closed	major		Core		fixed		Eric Pettersen				all	chimera
