+* adds greater use of `{fs}` over base file functions [#160](https://github.com/jmbarbone/mark/issues/160)
 * improvements in `todos()` and `fixmes()`
   * File extension can now be set [#170](https://github.com/jmbarbone/mark/issues/170), which by default includes `qmd` ([#163]((https://github.com/jmbarbone/mark/issues/163))) and `py` files
   * new parameter `ignore` to ignore any files
