There is a very useful tool called "Subfolder Menu" in an old and not up-to-date software called "QTTabBar". Here is an example of how it works. Form any directory, you can click a blue arrow and traverse through the whole directory subtree without the need of clicking. This is a gamechanger for me, and I can't seem to find a similar feature anywhere else. Is this possible to do with Directory Opus?
Not verbatim. You can gain some of that functionality by adding this to the context menu:
Go FROMSEL FOLDERCONTENT
How to fine-tune the command:

Thank you for your reply, but I have just started trying this software,and I am not familiar with it. Could you please guide me through the steps you did to arrive to the menus shown in your screenshot? Sorry, but I haven't been able to find my way
You'll find the File Types editor here
But if you are just starting out, I'd recommend using Opus as it is. It's got dual file display and tabs, which provide a much more efficient and safer way of handling files and folders than a context menu. Leave that tool to FE, it needs it - Opus doesn't
Thank you so much, it works flawlessly. And yes, my idea was to be able to get rid of the tool and focus my worklow on DO, And being able of using my favourite function in this software has changed everything, so I'm staying for the long run. Thanks again!!!
Just one last thing related to this. I'd like to find this option more easily than any other on my context menu. Is it posible to give it a background colour, or underline the word, or even make it bold?
I don't think it is. You could move the entry up and/or add an icon.
Good idea you had there, and in Dopus you can do everything.
start the name with --> or some symbol, you can also add an icon that lights up or start a new group, there will be some space in between.
This is how I have entered it now

It works flawlesly on my main lister, but is there a way to make it work also on the folder tree? as that is usually where it is the most useful.
It should work in the tree, but possibly not under the Quick Access (“Home” now that Microsoft renamed it) branch as that may show the standard Windows menus.
