The context menus are now consistent with that for map views:

Spectral Library View → rename/close/show.
In future this might get more actions related to the view only, e.g. copy / paste visualization settings, add to map canvas etc.

Subnode with vectorlayer symbol → rename/copy style/paste style/layer properties
In future there will be more subnodes, e.g. for spectral processing models or multiple speclibs visualized in the same Spectral Library View

Realizing that some things can be done fast I expanded the Speclib View Nodes’s context menu by some toolbar actions.
@Fabian Thiel note that the “Add Profile(s)” button now is only enabled if temporary profiles exists that can be added permanently.
