Just small aesthetic stuff - the column headings in the grid all kind of run together now. In the old Editor grid, it was easy to see the separate columns. Now the break between them is less pronounced, and the column headers all seem to run together.
A lot of our column names are rather long, and with them now bleeding together it makes it harder to read.
Also, the N&D button does not expand all the columns enough to see the column header. I still have a column with the … at the end.
