The vacation mode sounds interesting and it feels like hive.vote should have an option where only if your voting power is getting close to 100% will it follow one or many trails or automatically vote on some posts/comments that are always there and active, think like hbd.funder comments that benefit us all and don't go to a central entity that personally benefits from the rewards.

I don't know however how possible it is to create such an option as it may be costly in terms of API calls for the service to know when you hit 100% or even 99.9% to start casting trail/autovotes to save you from "wasting" mana and in tern curation rewards. This would however let you curate manually more efficiently as you stated, you would find yourself more often at 98-100% vp so your manual vote then would be worth as much as it can and you wouldn't have to worry about having to vote 10+ posts every day if you're fully manual.

Maybe @mahdiyari who's behind hive.vote could weigh in on the idea.
