awesome :-)

hm. actually, i think it's already quite all right: <del> makes a cell NA, if 
you don't double-click it. but it is indeed a bit unintuitive that for 
*string* columns, it's enough to double-click a cell to change its value from 
NA to "", whereas for all other column types the value doesn't change.

also, just a minor issue: the R console only shows string NAs as "<NA>", all 
others as "NA". don't know if we need that level of equivalence, but it might 
confuse some users to see a "string NA" when it should be a "numeric NA" (or 
whatever) in a cell.

a start could be more consistency: when you fill a string cell with more text 
than its width, it is truncated by "..." to indicate there's more. firstly, it 
would be better to color the "..." also in that light grey now, so you don't 
confuse it with actual string values; secondly, these dots are currently 
missing if the value ends with lots of space characters. this makes untrimmed 
values hard to see.

showing light grey quotes might actually not be so confusing. it could be made 
configurable via the format field (or globally).

by the way, is there a way to configure the font yet? for some cases, a 
monospace font would be more useful than the current default.
