I have not even knew so far that Steemleo has a DEX. It is good to know that it is fast and it has a built-in claim all button. I have not even tried it so far, but I probably will. Maybe I will use this instead of the Steem Engine, because that is often slow, and as you mentioned, Steemleo's interface has a "Claim All" button, and the Steem Engine does not have that button. At least not at the time of the writing of this comment. Maybe they will implement it later, if they see how important and useful/helpful it is to the users. I am not a developer/programmer, but seeing that the "Claim all" button is also available on PALNet and on SteemWorld (beta), it would probably not require huge efforts from the developers to also implement it on the Steem Engine. Thank you for the detailed description!
