Trying to go to the home page, I always instinctively look to the sidebar for a button labeled "Home". For some reason, Cohost does not have this, and I always have to remind myself to instead click on the logo in the top left corner (or top center on mobile).
I think this would be a nice, simple addition, that would especially be useful for new users. Nearly every other platform has a similar button, to the point where i'd consider it standard and expected. It's honestly rather strange and disorienting not finding one here, imo
For the record, such a button existed before the recent redesign. Perhaps they felt it was redundant or took up too much space.
