You can either add this function as it is to preserve =centaur-tabs= default filters and add any Boolean function that you want to filter your buffers (i.e =string-prefix-p= or =string-suffix-p=) like in this example with the "mybuf" line, or completely override the function with your custom filters if you completely know what you're doing.
