Hi Samuel,
from my opinion, generic text editor would never win against proprietary IDE, first because lack of knowledge in topic and second because of lack of resources (generic text editor need to support all languages, where explicit IDE cam concentrate on one). So spending of resources in this direction would be waste and never ending run after the leader. HE need to find such area which is not covered by IDEs: script languages without explicit IDE or just a tool for quick editing, when starting of IDE is too much.
Also building in all these features would convert HE in monster like UltraEdit with milions of features you never need. Creating of the plugins is a right way. Where syntax dependent plugin can gather all related functionality and can be installed by demand only by people who require it. This was already requested some when by Arthur. And maybe in such way debugger support for VBscript or JavaScript can come. Or some simplified compile, run commands for other languages or auto completion. But this is big work, and you really need to have a market for this. Because, I think, any way people would prefer to use dedicated IDEs instead of some limited tool when they do big projects.
About the 98/Me support. It is easy to keep it when it already done, and gives benefits against other editors do not having such support. But maybe yes, some when would be dropped, but do not know when.
Best regards,
Alex.
