Thank you for your persistences: My answers (in italics)
“It seems like a contradiction to me.”
No contradiction, the image I provided in my last post (also directly below) was from YOUR machine, as seen in YOUR post above.
No this is a clip from your image above.
"Are you on Cubase 15? "
Yes I am on Cubase 15
Windows 11 Build 25H2 (latest)
Incidentally both products have been freshly re-installed.
I shall include another pic with my whole MediaBay open in Current View, at the bottom of the thread, with everything showing. I shall put a circle around the area I think YOU mean. I do not see this button and have found no way of bringing it up. Really puzzling.
" I noticed that creating custom categories/subcategories isn’t supported the described way in versions prior to C15:"
OK, though I am not running any other versions of Cubase on this machine only C15.
This Image you included (directly above) - Accordian etc… I can see this too, but only this.
Not the other [remove/add user] box shown again below - from your system.
Deleting mistakes
You solved this problem. Fantastic! Thank you.
I had hunted for this function for hours!*
I found this box where you indicated, but it was initially hidden, by no means easy to find!
Two rules to see it. First you must be in defined view, second the Gear Icon next to the Defined label, must be clicked.
Finding this gave me hope that I might find, by some similar wizardry a method for revealing the other buttons +/-, but no luck.
Could I ask you please to send me an image of your whole screen with the Attributes Column displaying the Category/Subcategory panel we have been discussing. I think your explanations are clear, but it may be some obscure thing…
Here is my system pic for the whole Media Bay. I indicate where I have been looking and not finding, the cited function box:
I think we might be talking about different locations?
