Currently there is a lot of functionality that in theory does not require an account, although Voyager still prompts you to create one.

Whilst I now have one, I initially intended not to.

Either way, there are a good amount of features that could be adjusted to fit guest / offline accounts, including:

• Changing the guest instance
• Allow saving posts locally as guest (not synced, ofc)
• Allow changing subscriptions as guest (there's already some in guest view anyways, I figured being able to change them would be nice)
