currently, the “show notifications” setting applies to all profiles.
There are situations where you want to change this setting per profile instead, especially after the multi-profile notifications feature was introduced.
maybe do not add additional switches, but just treat the existing ones as per-profile. this is also true for most other settings, so, it also makes sense from that point of view.
I think the main problem is muting other accounts, so while it can be nice to change notification settings per account, for example giving each account their own notification sound (in the future), I think the mute state might be better also shown in the account switcher?
