The Designer has the two columns on the right fixed and very narrow, which prevents working with the data shown inside them. See image.
Curiously, the central design of the user app has unnecessary blank spaces on the sides (even with the "Monitor" format).
Also the check to show components with the visible property put in FALSE not runs.
See you the attached image to can verify it:
I tested that the "NEO" User Interface has solved the mistake when we are scrolling in the Blocks. The clasic User Interfce has not well this function when we have a lot of Media items.
From now I will work whith the NEO User Interface because it runs very fast and I have not problems in the compound blocks. The Find function is very well to help the programmers. And the scrolling Blocks is running well.
