Other things we are working on

Even though our main focus is on the stabilization of TeXmacs and to make it more suitable for developers, we intend to continue some time on the development on new features. A few points currently have our priority:

• Further development of the graphical drawing mode. First, the upcoming support of Cairo, OpenGL, etc. should improve the rendering quality. Secondly, we intend to allow the user to create new macros, either by explicit constructions or constrained-based constructions. Finally, we would like to incorporate several features which are typically found in editors of vector graphics, such as Inkscape.
• Extended features for computer algebra sessions, such as automatic folding of large expressions, lazy output (with subexpressions which can be further evaluated by clicking on them), cas-aided writing, etc.
• Providing more semantics to mathematical formulas by providing a simple way to construct parsers and pretty printers and to use them for establishing a bijection between presentation and content markup for certain well-defined languages.
• Continue the development of remote TeXmacs servers for providing web-based services in combination with TeXmacs. These services comprise chatting (with mathematical formulas) and collaborative authoring.
• Development of universal spreadsheet tools, which can be connected to any external plug-in for doing the computations. In a similar vein, external plug-ins might be used to draw graphs of functions in the graphical mode.
