First of all, I've got to say that this plugins rocks! It's very light and user-friendly. I have only one issue that I reckon is not a big deal to hack/fix/add an option in the next version of Polylang.
My problem is that in case of untranslated categories/posts, polylang language switcher doesn't show the link to that category/post but to the homepage. For example the category of posts Rezultate (Results) has not been translated and when you are in the default language and hover on the russian flag, you can see the url goes to the russian homepage (http://bikeportal.md/category/results/). The same goes for single posts.
The thing is that I don't to translate these posts and I don't want to duplicate them either. So I thought if I translate categories and assign each post to 2 categories (default - translated), this post would appear in both romanian and russian posts list. Unfortunately, I can't assign one post to the counter-language category. If only that was possible, I think all problems on my website would be gone.
Any advice on this problem? I would be very thankful.
