[galaxy-dev] ToolShed for Visualisation Registry?

I was wondering if there is a possibility of a 'Tool'Shed for Visualisation registry plugins(custom plugins, developed by users/developers)?

The motivation for this comes from a small 'tool' I wrote for visualiing fastq phred scores using box plots[Still under development] here: http://saketkc.github.io/biojs/src/test/javascript/TestPhredScoreViewer.html

I am relying on d3.text to read my fastq, but I believe I could handle this in a much better way had I written it for Galaxy's Visualisation registry specifically. For e.g. I could fetch fastq scores line by line using Galaxy's API, which would make my task a bit easier.

I could always keep this to my local instance of Galaxy, but a 'toolshed' or 'registry' for visualisation would help.
