As a fellow WPML user and user of the pro version of NotificationX I would love to see that become an option (at least for comments). And yes as detailed by the team it’s now all shared among languages.
But which content get’s shown by NotificationX heavily depends on what you are using as a source. For example for comments it could perhaps be handled even better by also storing the ICL language code of the item the comment was made on, which can then be filtered on showing.
But if you are showing woocommerce purchases … well that does not contain user generated content (it only shows the purchase), and so only serves a simple translation. (which is still possible with current WPML / NotificationX)
Just thinking out loud here.
@tushar284 there is no better way for us endusers to discuss / talk about feature request then here I guess? As there is no general support forum for Pro members on WPDeveloper.net (or am I mistaken?)
Perhaps setting something up like Trello / UserVoice for feature requests would be an idea? That way we can still voice what we would like to see, others would be able to show interest and you as developers could look into what is ‘hot’ and feasible.
Anyway keep up the great work guys!
