Dear Steemians,
Who doesn't know about Steem Upvote Bot Tracker created by user 
The #1 place for information on voting bots and other options to promote your posts on Steem!
quoted from the tool itself.
It is really a great tool to find which bot to bid to promote our posts. It lists some very useful information that we need to know about the bot, such as:
- Vote Value: the total value of an upvote at 100%.
- Min / Max Bid: that is accepted by the bot.
- Min / Max ROI: that is claimed by the bot.
- Min / Max Age: of posts that are accepted.
- Total Bids: that has been accepted so far.
- Max Suggested Bid: that will not cause negative ROI.
- Last Vote: last time the bot upvoted.
- Next Vote: next time the bot will upvote.
It even has the up-to-date information on performance of each bot in term of ROI, the current and last ROI. We may see the information from button
Actions → Details
Sometimes we want to see all these current and last ROI in the front page altogether with other information. So that we may know the actual performance of the bot the we are going to bid, without having to click on Actions → Details button on each bot.
Now 
See the modified tool here
The front page now has current and last ROI too.
You may find the modified source code here

Hope it may help us further to find the right bot to bid.. :-)
