I notice there is no help ‘documentation’ showing any more on the fields. For example in this case the “Last_Login” field should nudge me to ensure i use simplified extended ISO date format. But that helper text is now missing.
i appreciate space is of a premium, so it’s fine to have them on a tooltip or small unobtrusive icon

Also, could i please ask if you can make the “conditions” a different colour to the “arguments”? Maybe dark green for conditions or something? 
simple but just helps speed things up further & prevent brain visual overload.
Very nice! Now it’s so easy to search icons!
And how about adding options like this? If the goal of the new editor is faster, more intuitive, and easier control, I think this kind of UI could be very effective.
The new editor has a lot of empty space, so it feels like we could pack in plenty of useful features there. What do you all think? I’m curious to hear your thoughts.

With the current method, you always have to click min and max first and then adjust, but if we change it like this, I think it’ll make setting up a responsive layout much easier.
Plus, if you could toggle between pixels and % and have custom breakpoints linked by default, I think it would feel pretty much perfect.
There are new updates you can find here: New updates to the redesigned property editor!
