Computer wise, while I know we need Graphical User Interfaces, I enjoy the clear power of a command line (and reveal codes in Word Perfect) I regularly use Windows keyboard shortcuts instead of pointing and clicking all over the place. In this I often feel like a dinosaur. I am glad that Logos 4 keeps a Command Bar which can save quite a bit of pointing and clicking, but I wonder if there are some places where there needs to be a more graphical front end also.
Prime example of this is collections. The new syntax for the dynamic collections is quite simple to me, but the more I think about it and see people talking about it, the more I think that there needs to be a better way. For the life of me, I don't know what it is since I LIKE the way you have implemented it, at least if you fix the metadata.
While some of the morph and syntax search is a bit easier than it was I wonder if you should reconsider having a graphical query interface as well. This seems to be the way people try to deal with computers now.
