Updates to Trace include an improved toolbar and editing xrefs while in Edit Drawing mode.
Trace Toolbar
The Trace toolbar now more clearly shows whether you're editing the trace (TRACEEDIT) or editing the drawing (TRACEVIEW).
Additionally, the Settings drop-down menu now can be pinned so it remains displayed after the cursor hovers away. You can also drag the drop-down to a new location, as you would a palette.
Edit External References while in Edit Drawing mode
While a Trace is open, in edit drawing mode, REFEDIT is now enabled, meaning you can now make changes to xrefs.
