I don't know if this is possible, or maybe there is some reason that the right sidebar only shows the info about lemmy world? I would much prefer to see info from the community i'm visiting, instead of needing to click on the three dots at the top. Speaking about the three dots; in a sidebar with community info, the info to subscribe, create a post or block could be listed there as well. I personally do not really care for those three dots. If that lemmy world bar has to be there for some reason; maybe it can then be shared with community info? That you see the community, but if you scroll down, you still see the lemmy world information?
Btw, don't get me wrong; i really like Photon and it is what i almost always use.
Update: fixed in v1.18.0! making an update post now!
