Showing multiple categories for post

On my blog I frequently use multiple categories on blog posts. Customify shows just one and the the first one in alphabet order, which is usually not proper.

After examining code i found out that there is option to display multiple categories but it is disabled.

setting is in customify/inc/blog/class-post-entry.php at line 23

'term_sep'       => _x( ',', 'post term separator', 'customify' ),
'term_count'     => 1,

After I change it to

'term_sep'       => _x( ', ', 'post term separator', 'customify' ),
'term_count'     => 0,

I get list of all categories nicely formated.

Note, for term_sep I added one space after comma and changed term_count to zero.

As this is hard coded, this change will not survive next Customify update.

Can we have this configurable in any manner, please?

Is it possible to change these values from custom functions?
