A simple addon to manage and keyframe the visibility of objects by batch. This affects both rendered and viewport visibility.
Object -> Show/Hide
This addon has two modes: "Show now, hide next" and "Hide before, show now". It will insert a keyframe on the current frame to enable visibility, then depending on which mode you choose, the addon will insert a keyframe before or after the current frame to hide the object.
No code change - adjust .toml manifest to match bl_info in init.py
This extension does not require special permissions.
Can you add 'hide now, show next, btw very good plugin
