There is nothing amazing – just small things as Autodesk themselves say. I have tested a couple of things and have some comments on the first of them:
Remember Column width spacing in Type properties dialog
This one is in the Family Editor – in the Family Types dialog box (the one with four blue squares, which I never remember the name of).
When you open that dialog box, the column widths are never arranged how you want them: The formula width is too small if you want to add formulas; the ‘Lock’ column is always too wide etc.
In previous versions, after you had rearranged the widths, then closed the dialog box, the next time you opened it, those darned column widths were back to standard. In addition to this, when you make the dialog box wider, all the column widths expand; if you make the first column wider it often seems to make the ‘Lock’ column wider too…
