MattHarrigan Just sharing my two cents here. This too is one of the things I miss most on GrapheneOS. LineageOS has a whole section for status bar settings, including other simple things like "show seconds" on the top left clock.
GrapheneOS is an AOSP variant focused on security and privacy, and delivers leading security and privacy. Other AOSP variants, such as LineageOS, are focused on other things, such as supporting many devices and supporting devices after vendor support ends. It seems unlikely that GrapheneOS will ship all of the convenience features of LineageOS, and unlikely that LineageOS will achieve the security and privacy of GrapheneOS.
MattHarrigan Not a big fan of installing more apps just for these features (my battery life is already trash because of so many apps lol).
It is possible for individual users who want some specific features to add them to GrapheneOS via apps, but it is not feasible to add security to LineageOS by installing apps. It seems likely that this situation will persist.
