    1. COi'd love to know the answers. There are persistent rumours that the ESS guys will get around to this, but I haven't seen it yet ...

    2. COI have something at home that basically works. It is based on mumamo-mode and markdown-mode. I had to make a couple changes to mumamo-mode to get it to work though, explained here: https://bugs.launchpad.net/nxhtml/+bug/626039/comments/5 . I'll follow-up here with an answer after I get home and remember what I did.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
