Hi!
Try doing this, because I find I work much more quickly in this mode. To me this feels very similar to Axure 8.
Upon creating your first command, double-click it. The dialog below will pop up. Then do all of your work inside of it. You can do anything in this dialog that you can in the other UI, but barely anything is hidden or hard to see. (You still have to mouse-over to see the button that adds a condition, but you’ll get used to that pretty quickly.)
In fact, I usually create a dummy command as quickly as possible in the other UI and delete it once I have this dialog up.
[Edit]
Oh! Look at this! The tiny button at the bottom of the interactions pane goes straight to this dialog, so no dummy command needed.
