If changing this requires you to be an admin of a board, I wouldn’t consider this 100% control. I am not an admin on that board, nor am I on this one.
With that said, I’d like to debate why this is the default configuration (and why the delete icon is not next to the edit icon). I have a total of 4 buttons on other’s posts (or on my topics) and 5 buttons on my posts, if expanded. 5 seems totally reasonable to me and I don’t see the necessity of hiding that one extra button and an additional one behind an ellipses button instead.
Is the number of buttons different for staffers?
