         * JB: Should only include things that are significant improvements.  Too many modest improvements don't look like you need $1B when SO is $100M.         * JB: Should only include things that are significant improvements.  Too many modest improvements don't look like you need $1B when SO is $100M.
         * JD: But these small things add up. Maybe each of these factors of 2 are put together in one section.  Like the parameter constraints beyond LCDM.         * JD: But these small things add up.

 +      * This material (and more) is in the text. Table is not exhaustive.  Is it worth the time investment to make this? Not clear that we can do so in next few weeks.
 +      * JD: Mentioned CIB.  We could say CIB is/can be involved in delensing.
 +        * SH: This is a good example.  CIB is mentioned in text, but is not in table.  Work is needed to add this to table along the lines of 'current knowledge' for CIB in table.

 +  * AT: these updates don't have new ideas from EC members. 
 +  * AT: None of these are final.  Hopefully these provide all the elements we want. Opinions? 
 +  * AT: Just a comment. Having text on the cover is uncommon.  But it seems we have decided to go in this direction. 
 +    * JB: No text on cover isn't hard rule.  Like the one with line of science points. Scattered science topics is just cluttered.  AT: true, text on cover is ok. 
 +  * SH: One concern was if the text on cover is obviously science goals.  Or people might think we were just describing the universe. 
 +    * JB/JD: as long as the same language is in EC they will get it. 
 +  * JB: Like version 1 because it shows spacecraft.  Like version 2 because it is new/different and looks cool. 
 +  * JD: Don't like science topics scattered around. Keeping the line is better. No inflation in science topics? 
 +    * SH: my task to rewrite topics. Anyone want that task?  . . . no response . . . 
 +  * AT: imagining 2 new versions.  1st, Top left but with some maturing.  2nd, eye with spacecraft at center.  PICO text moves.
