Hiya...ST v3 has a nice XML tagged output that shows which template
generated which output. I'd like an interactive thing that's easier to
read for ST v4  I'm including a mockup.

It starts with a window with the generated output.  As I mouse over a
section generated by a template, it highlights (one at a time) with a
box or whatever.  I can collapse output for any expression/template.  If
I hit "get info" key it would pop up a dialog showing the template
pattern and the attribute table (an inspector).  It seems like I'd need
to detect mouse movement over a textpane and then expand and collapse
sections (hopefully w/o having to do much; perhaps replace the char
sequence with a new "collapse icon").  Intellij does it but I wonder how
much they rely on Swing to do the fancy stuff they do in a textpane.
Any thoughts about which components to use or avoid?  Any architectural
suggestions?  Everything would happen in the text pane, except for the
inspector which is probably a kind of treeview or something.

Gerald probably has lots of suggestions as he's done something similar I
think for Eclipse.

I can't get to this for a while, but wanna start thinking.

Thanks!
