How to see only the categories assigned to an image

[WhiteTiger]

Having purchased image galleries, many of them already have categories assigned.
In the categories panel I see all categories, assigned and unassigned. The problem that there are dozens, it is not easy to see only those assigned to an image.
There is a filter, but that hides the assigned ones.
I would like the opposite and hide the unassigned ones.

You can look at the "Category Sets" panel ( with View > Panels > Category sets enabled )

You can also set a label :
- Settings >(Browser) Thumbnails > Labels
- Select a "Custom" label
- Push it to the right side
- Select it, and add {Categories} in the bottom field . Ok

Or a tooltip
Settings > Browser > Tooltip
Add {Categories} ...

(here we could use the black arrow at the bottom > Extra > Categories)

Thank you, your two suggestions help a lot, but...

You can look at the "Category Sets" panel ( with View > Panels > Category sets enabled )

This does not solve the problem because there are dozens of unassigned categories and the assigned ones are "lost" in this large number.
It was in this panel that I was hoping to see only the assigned ones.

You can also set a label :
...

Now I see a row of categories, but only the first few are listed.
I was hoping to see them all in the panel.

...
Or a tooltip
...

Now, to see them all I have to use the tooltip, but to do that I have to bring the mouse over the image.

Exploring "Settings," I saw that I can put {Categories} in Title Bar. That's not what I wanted, but at least I can see all the categories in a row.

In "Category Sets" pane, only assigned categories are shown ...

You can move this pane, even out of XnViewMP window
