The update was intended to completely eliminate the need to send commands to @tipU via steemit wallet. Instead all the buttons allow the investor to manage his investment without need to send 0.001 STEEM to @tipU to make any changes.
If you're sending @tipU to send tips or subscriptions - you can now both send and withdraw the deposit directly from the website.
From this section on top-left you can customize your payouts:
The "next planned payout in..." section also has a "payout" button - clicking it will trigger instant payout.
This section presents how much STEEM and SBD, that come from upvote requests payments, was added to your profit. It's always payment x your share. I think it's a nice way to display the transparency and the fact that @tipU does not take any cut from the payments - all is distributed to the investors.
Here you can see detailed info about the recent payouts you have received from @tipU - thanks to this this data does not have to be send via memo with the transfers so there's less spam on the blockchain :)
Not it's time to update the investor's guide (the old one got pretty outdated) and also implement some tooltips on the website to quickly explain the features.
