When using the "Share with Proton users" aspect of shared calendars you cannot choose limited view, only full details or edit permissions. Currently Limited view is only available if you use the Share with anyone and create a link. This seems like an easy change, I want to be able to share my calendar without a link (that could be leaked), but also not have to burden the one person I wish to share it with with the curse of knowledge (the minutiae of my every movement.)
