The spreadsheet user interface is most useful when the data naturally fits into arrays. For many everyday applications, this is the case. I don't see it for graphics, unless you are actually talking about a mosaic. If you ignore the conventional meaning of the word "cell" in the above, though, what you have is very like a programming language. The traditional UI for a programming language has been ASCII text. For a different one try a tree structure with crossreferences to labelled branches. Something like that has been done for the scripting language in some popular war game -- I'm not sure I ever knew which. -- hendrik _______________________________________________ Gegl-developer mailing list [email protected] https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
