PLT Scheme’s user interface library is called Mr Ed. It is used to provide DrScheme to thousands of computers running Windows, Mac OS, and UNIX. It “just works”, and does so well; it is a fine graphics toolkit. MrEd Designer aims to make Mr Ed even easier to use!
Peter Ivanyi now maintains this application.
MrEd Designer 2.1.2 is released; it now supports tab-panels.
In MrEd Designer 2.1.3:
- tooltips are added for the main buttons
- the no-border style for the tab-panels is fixed.
