I'm totally new both to WordPress and PHP, i.e. a dumb user, so sorry if the question is dumb too.
I think you plugin is great, it makes anything I need but one. I'm using a predesigned theme with a special home page based on slides. The content for these slides is provided through special fields under a configuration panel, so I can't establish language relationships between home pages and even worse, I'm forced to keep a multisite environment just for the home page in the alternate language.
The problem is that I can't link the alternate language switches in the menu bars of both home pages (stored in different sites) to the home page in the other site. On the other hand, under WordPress I do can provide a custom link for "Home" in the menu bar, so I could point it to other site without any problems, but I don't know how to do that for the Polylang flags.
Please, tell me this is a dumb question and there is an easy solution. I'm a good C++ programmer so if need to get my hands in PHP, I could give a try. I know there is another plugin called "Multisite Language Switcher" but I prefer this plugin.
