I realize this isn't happening for anyone else, but for me at least the toolbar customization is not working as indicated in help docs.
Settings>Customize displays a completely different set of toolbar buttons, making it impossible to edit anything. Once customize dialog is closed, the toolbars return to "normal."
I'm obviously doing something stupid/wrong, but can't for the life of me figure out what that could be.
How do I get the toolbar buttons to remain the same when I go from Dopus to the customize dialog, so I can edit them?
It looks like you have put a Favorites button on the top-level of your toolbar.
Favorites is one of several Opus commands that "expands" to generate multiple buttons when not in Customize mode. When you go into Customize mode these dynamic buttons collapse back into their root commands which is what you are seeing.
In the case of your screenshots, you have two groups of three buttons, followed by a separator, a shield icon, what looks like a PDF icon, and then to the right of that is the Favorites button.
You probably don't want that on the root level of your toolbar so just right-click it in Customize mode and select Delete to get rid of it (or drag it into a sub-menu if that's what you prefer.)
I probably wasn't clear. As in the screen grabs, the Favorites button disappears in Customize mode, so I am unable to right-click, drag, delete, or anything, really.
Do I need to be another mode to get rid of Favorites button and "Open in Tabs," which I also want to be shed of?
