Nice one man. You might not realise it but you basically made an open source alternative to Patreon here. It may not work based on time (i.e. x dollars per month) but taking the average number of posts of a given user someone follows one can set a desired voting power and auto vote their posts to give them guaranteed income (well as far as you can guarantee I suppose).
The scheduling could be improved though, I've scheduled something today and it posted it 4 minutes after it was supposed to. It was pretty weird, like the counter showed -340 seconds and the like. It would be better if the scheduler worked by date and time rather than set hours in advance. Also is there some software limitation that makes it 100 hours in advance maximum? Some people have their stuff planned out a month in advance (especially when it comes to collaborations with set release dates and the like). Does the scheduling work only when I'm logged in and have the SteemAuto page open or does it work always? Because that's kind of the point of scheduling, to do it when you're away from the computer (for instance AutoSteem doesn't publish when you haven't got the page running in the browser, which tbh defeats the purpose of a scheduler).
Sorry if it's off topic lol
