 == *features* ==
 The _features_ object (optional) is used to enable/disable and/or set options to specific features of Melange lists. This can contain:
   * *cookie_service*: is an (optional) *object* which can contain only one key, *enabled*, which is a boolean. By default is enabled, so if the object is not present the cookie service will be enabled, to be back-compatible with current lists. If it's enabled, the lists will use a cookie to store/retrieve their state between sessions.
-  * *column_search*: is an (optional) *object* which can contain only one key, *enabled*, which is a boolean. By default is enabled, so if the object is not present the column search will be enabled, to be back-compatible with current lists. If it's enabled, each column in the list can be filtered using a input (either text or select) which is appended at the top of the column itself.
+  * *column_search*: is an (optional) *object* which should contain to keys, *enabled* and *regexp*, which are booleans. By default is enabled, so if the object is not present the column search will be enabled, to be back-compatible with current lists. If it's enabled, each column in the list can be filtered using a input (either text or select) which is appended at the top of the column itself. If *regexp* is false (true by default) the top-right checkbox which enables regexp search won't appear. In this way column search can be enabled with or without the option to search by regexp.
   * *column_show_hide*: is an (optional) *object* which can contain only one key, *enabled*, which is a boolean. By default is enabled, so if the object is not present the button to Show/Hide columns will be enabled, to be back-compatible with current lists. If it's enabled, a button at the bottom of the lists will appear to open a dialog to show/hide columns in the lists, as well as a checkbox on the upper right to enable/disable regexp search.
   * *search_dialog*: is an (optional) *object* which can contain only one key, *enabled*, which is a boolean. By default is enabled, so if the object is not present the button to Show the advanced search dialog will be enabled, to be back-compatible with current lists. If it's enabled, a button at the bottom of the lists will appear that opens a dialog box to do an advanced search inside the lists.
   * *csv_export*: is an (optional) *object* which can contain only one key, *enabled*, which is a boolean. By default is enabled, so if the object is not present the button to export to CSV will be enabled, to be back-compatible with current lists. If it's enabled, a button at the top right of the lists will appear that opens a dialog box with a CSV export of the list.
