I second this opinion.
There is room for some improvements in useability, for example syntax highlighting or an improved search feature (wildcards, regex) etc.
These issues have beeen suggested before, and these issues can be found (to some degree) in third party editors - but then, these editors are not "specialised" in our tiny, exotic language called MSL - thus I'd like to see them in-build. smile
But, instead of a "auto syntax completer", I think a general revisal of the helfile would help all of us - and this revisal (fixing small errors/ambiguous passages, adding some undocumentated commands, adding more examples [!] etc) would be a large-scale project none the less.
