Hi there!
First of all: Great program! Easily beats many commercial prods.
Can I make a little suggestion? I would very much like to see automated save. There has been a couple of times now when my machine has crashed or I accidentally have clicked "no" to the "save file"-prompt when exiting.
Could there be "enable autosave" and "autosave interval" fields in "preferences"? Or maybe an option to save whenever the file has changed, if user wants so?
Regards,
Ville
PS. Great program!
