Several toggles should be added to the interface, when accessing the "Search Text" function in "Snippets":
    To better control the search behaviors.

    Namely:
    |1| Word-Only [ Default: false. Equivalently wrap the pattern in /(?<![^\W_])...(?![^\W_])/. ]
    |2| Case-Sensitive [ Default: false. ]
    |3| RegEx [ Default: true. Treat the pattern as RegEx or literal. ]
    |4| Multi-line [ Default: true. Use "m" flag for RegEx. ]

    The search settings should persist, between different invocations of "Search Text" on the same page (and not across pages / browser tabs).
    A button to quickly cancel previous highlighting would also help.
