The Kashmiri language Wikipedia (kswiki) uses both Perso-Arabic and Devanagari script pages. In this regard, it is similar to Konkani Wikipedia. Currently in Konkani, use the सांचो:VR, सांचो:VD and सांचो:VK templates to link pages in the three scripts with each other. Kashmiri Wikipedia used the same system too.
However @Ernesztina has recently introduced a Toggle system in Kashmiri Wikipedia. The Toggle system creates a better linking and navigation between the different script pages. An example of that can be seen here - ks:कॅशीर. More examples in the incubator Wp/sgh can be found here
I propose that the same system to introduced in Konkani Wikipedia. Here we have three scripts and the toggle will be more useful than the current templates.
I request anyone with the technical know-how on Toggle system for their input and help for implementing it in Konkani Wikipedia.
