Locale management features
It would be very convenient if you'll to add a new locale management(merging/splitting) feature, since plesk2smb.php is absent since Plesk 18.0.31:
Although if that's possible, to adapt plesk2smb.php to the next versions of Plesk that'd be good.
Plesk Tech Support shared this idea
It is planned in scope of integration with CrowdIn localization system. Big files like common/application/admin/resources/languages/ca-ES/messages_ca-ES.php will be split into small chunks similar to en-US locale.
