Re: [Gmod-ajax] FW: JBrowse: override metadata display in 'About this track' box

[Colin <col...@gm...>]

I wish I could say that there was a really elegant solution to all this. It
is kind of a clunky solution to use all these fmt callbacks so to make it
work currently is not elegant. But, if you want, some workarounds include

1. Adding a new field cannot be done straightforwardly, you can create a
"dummy" value in the metadata section of your track and then use
fmtMetaValue_dummy to customize it
2. fmtMetaValue_fieldname can modify existing fields also
3. To remove a field, return null from a fmtMetaField_fieldname

As this applies to hundreds of tracks that sounds pretty annoying. If you
want to formulate this as a github issue then please provide detail to
reproduce and what you expect to have.
