This is fantastic . It seems to me it is already very useable, and you guys are pushing it toward perfection :-). They do say that last few percent of a project takes a lot of the effort, and you guys are sure putting a lot of effort into it. I will definitely study the tutorials.

I have tried looking at the program but it is difficult for me to get my head around it, especially since I am not up to speed on Python. Is there a flowchart in existence for the program?
I think a flowchart would help me to understand the program flow and therefore assist with understanding the code. I know you guys are super busy though, so please consider it a low priorty wish.  I'm sure I will be able to get great results from this program whether I understand how it ticks or not  ;-).

Cheers  and kudos to you guys.
