The reason why I want this in core is not because there is no other way to get it. Asides from the functions usefulness; once we have this simple function in core it opens the door to many other language functions. Such language flag selector function could be extended to other functions. Mind that I specifically suggest a drop down selection, not an overlay.
But: if he keeps waiting for his suggestions to be added to the core (which address back to 2015 or something, that's 2-3 years at least!), well then good luck.
I see it differently. Quite a lot of my suggestions have ended up in XenForo 1 & 2. I post suggestions here for this reason.
I use 95 addons and many modifications. Many of which are for basic stuff and many addons I used in the past turned out buggy and conflicting. I hope to see XF grow to a point where its no longer needed to install 50 addons for base level stuff that many need. A language flag IMHO is base level stuf.
In regards to flags themselves: There are some great CSS flags available, or SVG or sprite. The use of old fashioned image icons is deprecated IMHO.
I think the demand for multilingual functions is underestimated. Currently if you run a multilingual site, then most likely only the main language part of the site will survive. If you happen to run a successful forum in your niche then it makes sense to expand into different languages as well. But its not possible. Google will not even index a section in a different language because you can only set one main language. The interface is not there. Language packs do not always make much sense to the reader. Therefore it will likely fail. Many will not even start with it. Its easier to just go to Reddit.
Conversely, Reddit thrives from this weakness of forum software and its an important factor in Reddit's growth. Members have begged me for a Spanish or French section. Due to the lack of functions I had to decline. Guess where they ended up. Yup Reddit.
The approach that I see admins take is to have multiple installations of XF. But that is hard to manage and track.
I concur that multilingual functions are not for everyone, but I do believe multi-language functions are appealing. Thats the point of the voting system for suggestions. If no one votes for it then most likely it will not be implemented. If there is demand then this will become obvious through votes. I have stopped posting just any suggestion that I think is useful like I did in previous years. There is just too much pushback. All suggestions I post now are because I think its significant. Votes will make this clear.
For me, the lack of language functionality is one of the main pain points for XenForo, because of the devastating effect it has. I don't think I am the only one who considers it so important.
Hands down, if admins do not even try to understand or play around with XFs TMS, then this is their fault and not XFs.
I do not concur. I really do not think XenForo customers should be required to know CSS and Template Editing. Some do not even know how to use FTP. Personally I am a fairly proficient XF1 webmaster; TMS, phrases, stylevars, replicating and modifying code, and some CSS/style editing is clear cut to me. I am however not proficient in CSS at all.
