[galaxy-dev] Semi-hidden "advanced" options?

Hi all,

Many command line tools have a lot of options - typically there is a short list of main options which will be commonly used, and a larger set of "advanced" options which are rarely used. I'd like to annotate the options in the XML file in this way, so that the "advanced" options are hidden by default.

What I have in mind here is something like the NCBI BLAST web interface, where at the bottom of the page there is a little triangle icon next to "Algorithm parameters", clicking on this it expands to show more options.

I've been reading the docs and don't see any mention of this kind of thing: http://bitbucket.org/galaxy/galaxy-central/wiki/ToolConfigSyntax

Have I missed it, or would this be a feature request?

Peter
