Is your suggestion for improvement related to a problem? Please describe.
I can add a new custom BST style in JabRef for entry preview but I have no option to remove it.

Describe the solution you'd like
Add a right click option to remove the style. This should only be possible for bst styles.

Additional context
Example bst files can be found in jabref/jablib/src/test/resources/org/jabref/logic/bst/IEEEtran.bst
