This is not about a bug! I just follow the guidelines at Wikipedia Village Pump about proposals for changes in the software and post this here.
I just have a suggestion of a very general type: Would it be possible to add a means to switch language from every Wikimedia page? Some pages contain the possibility to switch to another language, but some have not. I am multilingual, and therefore would need such a feature quite frequently. If there is no link to other languages, or the language I want to go to is not listed, it is always quite awkward to restart from scratch at the homepage.
