The ability to resize the Style window is a welcome addition. But just one snag. Open Format > Style. Click on the right-hand edge of the list of styles (left-hand panel) and make it narrower. Close it then reopen it to confirm that the width is still remembered. Now close and reopen the program and open the Style window again.

Expected result: The width of the left-hand panel is remembered.
Actual result: The left-hand panel returns to the default width.
