Hi there !  
I'been working with Node-Red some time now and I've created a nice and full of widgets dashboard that fulfill my application's requirements.

The current issue is that on each of the four tabs suddenly appeared a lot of 10 x 1 spacers.  
Before the that I used some 10 x 1 spacer but a few of them.  
I believe but not sure that that is the reason the dashboard is unresponsive.  
What happens when I'm trying to delete one of them editing it and click on delete button  
it take for ever , I mean the whole dashboard freeze.  
Before going on with this code I would like to know if what I'm intending to do with node -red is  
viable.  
My project is to control N machine for one customer.  
I am planning to use one tab per machine. Every tab should show data info from an independent  
hardware platform.

I have not extensive experience with node red and I'm wandering if that is achievable to implement.

Additional question:  
How is measure the dashboard's tab capacity or which is maximum widget's number on one tab?

Thank you for some help.
