See what I'd said at the end. ;) One reason not to include it was that font-request is cross-platform, but as currently written the get-font scripts have OS-specific file-names. Some method of determining which script to run based on View's version number could be worked out though, I'm sure. The get-fonts scripts might then need to be named get-fonts.3.1.r for Windows and so on. Carl.
