thanks for pointing this out and @tcpolymath noted that Steemworld also has a gui for it. Think this through with me though - isn't this in practice the exact same thing as selecting 100% power up, only it takes more steps and an additional 3 days after you receive post payout? What is the benefit? I don't see any big drawbacks, but having to take extra steps to achieve the exact same result is a slight reason to use 100% power up instead of conversion. I have seen some people saying that the conversion is preferable because it takes SBD out of circulation... but isn't selecting 100% power up taking the exact same amount of SBD out of circulation (or rather, causing the exact same amount of SBD to never be circulated in the first place, which is the exact same difference?)? Am I missing something?

EDIT - I guess it isn't necessarily the exact same amount - for a 100% power up post, the exact amount of Steem would be based on the 3 day rolling price average from the feed for the 3 days immediately before the post paid out, while if you use the conversion feature the exact amount of Steem would be based on the 3 day rolling price average from the feed for the 3 days immediately after making the conversion request.

EDIT 2: Thinking about this some more, I think the prime advantage of using the conversion feature is that you only have to predict the market for 3 days instead of 7 days. With how swingy crypto markets can be and generally unpredictable, with price movements based almost entirely on market manipulation and news stories, this may not actually make much difference in practice LOL But yeah I think it probably gives you a little better control I guess?
