Basically this (the green letters I added onto the screenshot)

Kind of a silly question but I can’t find it anywhere myself nor find any topic online haha.

We currently only offer the corner annotation style orientation markers (arrows, box, or human/custom 3D model):

We have a feature request to add top/bottom/side markers, but there are no immediate plans. You can add a thumbs-up to the issue to indicate that you were interested in having this feature, and if you want to have this feature in the near future then you contributions would be welcome.

> \- Allow customization of displayed fields:
> - Have a list of fields (DICOM tag…s, slice view options, text nodes) and allow the user to define any content in any corner by a format string. Fields could be drag-and-dropped or copy-pasted from some help text. For example:
> - Top left: \[ForegroundVolumePatientName\]\[NewLine\]\[BackgroundVolumePatientName\]
> - TopRight: \[ForegroundSeriesDate\]\[ForegroundSeriesTime\]\[TextNode:MyAnnotation\]
> \- Have a button to configure these in the view controller (set them for all slices/just one depending on slice link state)
> \- Allow displaying text nodes (this would make it easy for modules to show custom information in slice views)
> \- Allow more flexible configuration of what DICOM information is displayed
> \- Allow display slice position
> \- Reimplement in C++ for better performance and rename the module. Store current settings from scene (in view node) but initialize from Slicer.ini (similarly to other default view settings).
> \- Optimize performance. Need to check if text actors are not rebuilt unnecessarily
>  
> Related, but probably should be implemented independently from text information display:
> \- Display orientation marker letters at the center of top, left, right, bottom sides.
> \- Allow showing multiple scalar bars (foreground, background, label volumes, segmentations, ...) - probably as a separate feature, not as part of slice view annotations.
