IDE or Editor support for GM2?

[Hưng Hưng]

I currently use JEdit and modify their Modula-3 modes to support Modula-2. But it provides nothing other than syntax highlighting. No autocompletion, so code folding/unfolding. I know we have something for Emacs but the vast majority of users don't use Emacs, or even Vim. I'm from a younger generation who found working with these editors is torturous but no pleasure. Does we have anything better than just syntax highlighting? An IDE or Editor with support for autocompletion, at least with basic construct like BEGIN...END, FOR...END,... and automatic code folding/unfolding? If you know something like this please let me know. Thanks.
