modularization and how to write a profile/snapshot. E.g., how to update what <color> means in css3-multicol after css3-color becomes REC. (See 14 Oct telcon.) Or can modules never be published out of order?
fitting text size so that text fills a given width. Is this part of 'text-align-last' or separate? Who can edit the Text module if we want to include this feature? (Oct 14 telcon)
consistency between layout modules (Table, Template, Grid, Flexbox). It would be great to unify the ideas present in these, or at least define some primitives they can share.
collect last-call comments on MathML-for-CSS. Probably needs only 10 minutes: explain the draft (Bert) and collect comments, of which there are probably none.
