 * `ctagsymbols.tagsFile`: path to the ctags file to read symbols from, relative to the workspace root.
 * `ctagsymbols.hideDuplicateTags`: when there are multiple tags with the same name in the same source file, hide all but the first one.
+* `ctagsymbols.maxNumberOfSymbols`: never display more than this many symbols, regardless of the number of matches.
 * `ctagsymbols.minQueryLength`: don't process symbol queries shorter than this. May improve performance for large code bases since it avoids listing every single symbol in the entire project.
