One thing I deem as necessary for making effective use of this software is the ability to perform batch rendering processing. I have just worked successfully on a morph that involves 22 different layouts which were rendered to AVI. I then used Microsoft Movie Makie to join them all, but the most manually part of the process was loading files, changing settings then rendering. If you had a project wizard that allows you to specify multiple layout files and then allow rendering settings to apply to all.
If you can't give us that, at least give the option to process from a command line then I will write my own application to perform the batch processing.
