I see that today a new update was rolled out for 3.10.0. The whole ui for workflows got a refresh, but when working with rest api resource blocks it seems that the input window does not scale when you have data inside. It makes it very difficult to work with at this time. Any chance the team can look into this? Raw format is fine but JSON it sticks to a set size and you can't expand in any way.
Thanks for flagging this @DannyF! It's on the dev team's list to correct, I can report here when a fix has been pushed!
