Possible to disable asking to save a tab session when there is only one tab?

Hello,

I was wondering if it is, or could be, possible to get Multizilla to not 
prompt and not add a tab session for a window that has only one tab?  I 
currently have it set to always prompt because sometime I like to save 
my tabs and others not.  But when I manually close out my tabs and have 
only one left I usually am done and do not need it saved?  Just a 
thought I can do the extra click if need but.  Thanks for the cool add on.

Bob
