Hi, how can one hook into the GTInspector tags that can be filtered? Apparently I can assign a presentation to a tag with `<gtInspectorTag: #examples>`, however this works only if the tag name was already added. As this was done in GTInspector>>initialize, it makes the whole filtering idea quite useless (unless I explicitly initialize GTInspector, which is not the natural approach). Can't it just collect all the tags from the current presentations? Or can I somehow access the GTInspector instance from the `composite` argument? Thanks, Peter
