I'm a sysop in Arabic Wikipedia. I'm not a programmer so I'm gonna try to explain exactly my needs to avoid any misunderstanding.
I'd like to have portals while navigating offline in Kiwix. Kiwix team told me that it's made seperatly by language.
So what I'm asking is to add portal namespace into the content namespaces (https://www.mediawiki.org/wiki/Manual:$wgContentNamespaces) in the Arabic projects when creating ZIMs for offline use.
Please feel free to modify the description if it's not clear.
