how to change the display of records?

Hi, there is no option for that, I am sorry to say. You can see it in the source code for all database queries:
https://plugins.trac.www.ads-software.com/browser/gwolle-gb/trunk/functions/gb-get_entries.php#L185
It is all using sortorder as descending.

I am not sure if I would want to make this optional. If so, it would be through a filter. By the way, there is already a filter for this function, but I am not sure if it all would work correctly for your usecase.
https://plugins.trac.www.ads-software.com/browser/gwolle-gb/trunk/functions/gb-get_entries.php#L185

The filter gwolle_gb_get_entries_sql exists for this. The default documentation is at:
https://plugins.trac.www.ads-software.com/browser/gwolle-gb/trunk/docs/filters/gwolle_gb_get_entries_sql.txt
Strangely enough, that default documentation is doing exactly what your request is, changing DESC to ASC ??

Can you let me know how and if you manage?

Hi! in the gb-get_entries.php file I replaced ORDER BY datetime ASC and everything became as it should be…

Hi,
Please don’t do it that way. When an update happens, you will have to change it again. That is unmaintainable ??

Far better is to use that PHP filter that was mentioned, I will do my very best to keep that working in new versions.
