I can use text and rehearsal marks with the key commands (Shift+A/X), but the icons are no longer visible in the panel on the right side as they were in Dorico 3.5 Elements. Is this intentional or a little bug? In your videos I can see that they are present in Dorico 4 Pro.
It’s not a bug; there’s new functionality: these icons at the top of the right panel:
If the top one is selected you get the panels as in previous versions. If the bottom one is selected, clicking the buttons underneath launches the relevant popover. You need to have the bottom icon (the keyboard) selected in order to be able to see buttons for rehearsal marks and staff text, as these don’t have panels.
Thanks! Now I see them
