I was introduced to busy almost 2 months back and I've to say I'm totally glued onto it. It's a much sorted extension of steemit.com and works like a charm on phone screens too.
Notifications is the main reason I wanted something transparent and the search definitely ends here. About the bot upvoting. The chances and amount is quite low but then no harm trying. I use busy as one of my tags and 1/3 posts do get upvote from the bot.
