I use steemnow.com the most since it's the quickest for showing voting power.
Have you explored using the GINA, the notifier discord bot? I find it very useful, especially for handling mentions in posts. Probably has more notifications than you would want but very customizable for many use cases.
Nope. didn't even know it. Will check it out.
GINAbot is a great spy, you get DMs so you can see when your favorite people post, when someone mentions you, when a topic you are interested in is written about and loads more.
I have always been a little vote happy, manage to keep a lid on it a bit these days. I've been thinking about the 4 post thing actually. In an ideal situation when kids are not at home on holidays, I may actually aim for that.
