If you are German or British, then the flags will have little or no significance to you. If you speak German or English but are not from those countries, then the flags become a bit more of an issue. Not to the extent of being a problem, just a minor annoyance.
It does remember your choice, but it doesn’t automatically forward you. We are planning to improve this, but we need to do this backwards compatible, which is not that easy in this case. What you can do is to create a bookmark for the language.
For example you can bookmark: https://kurviger.de/en and Kurviger will be English by default.
You would think that it is that easy, unfortunately it’s not. If that would work reliable, we would do this. To make sure it works reliable, we need to reload the website and we only do this when the user agrees.
We are aware of that, if you have a better idea for icons that represent the different languages, I am all ears. Some websites use something like EN or DE, IMHO this does not look very appealing.
Automatically reloading is quite annoying, it will reload after the website is opened for a few seconds, so you might just start clicking. That is not an option I fear. We already have a few ideas for the future, but right now, there is no other option, sorry
Typically 0 to 1, you mentioned you do it every time you visit Kurviger
I doubt this would be recognisable given the current size of the flag. Then we would have to increase the size.
If someone struggles to read the name of a language, then they will not find this website friendly at all. I am all for making it accessible, but using access as an excuse for poor design does nobody any favors.
