@JulianEisel This appears to be the same issue as in #84101 just for the node editor, except that the group node previously didn't have the option to duplicate or create a new one in the UI. It might be a missing feature in this case.

There are more places with missed options:

Object:
{F9535609 size=full}
.
Node:
{F9535608 size=full}
.
Mesh:
{F9535607 size=full}
.
Particle settings:
{F9535606 size=full}

btw vertical margins for images are too big, so they separates from text too much, as if there emty line
Where I can ask for fix?

I believe D9946: UI: Default duplicate operator for data-block selectors is designed to fix this. I say “believe” as I am currently moving so I cannot test that diff as I am writing this from my phone.

Like @rjg says, the old design didn't support to duplicate there either. Only the particle settings one supported creating new particle settings (but not duplicating, it used the wrong icon).

D9946 indeed makes it possible to duplicate from all of these data-block selectors.

So not a bug here, thanks for the report nevertheless.

@JulianEisel
Older versions have button with digit, that allow to make node datablock single user duplicate.

So function is lost, unused options appeared.

so how it will be?
unused/unsupported options will be hidden?

I was asking myself the same. Yes we had this option before:

2.9 (works)

2.92

@Sanctus happily, this was reverted.

The proper solution is still to add duplicate operators for all cases as done in D9946. Using the user count button is a workaround, you can't even duplicate a data-block if it only had one user.

@JulianEisel in most cases you select existing data-block, and then make it single.
But I agree, duplicate may be useful too. In this case, usually, you set FakeUser for original (to keep it), then create a copy. So «Duplicate and keep original» will be more useful for single-user datablocks, that you want to copy.
