A front-end UI for network spaces
I think a lot about what I'd like to see in a front-end for network spaces and related applications.
I would like to have a user interface that permits mixing a command line interface with a GUI. One example of this from the past is that of CLIM, the Common Lisp Interface Manager and the Symbolics Dynamic Windows framework, which was a predecessor to CLIM.
This is not intended to be a completely general application framework (at least at the outset) or to create any sort of user interface. At the outset, it will be limited intentionally to a class of applications and interface styles.
