Thought it was a waste of time at first

But once I actually got into it, its not difficult at all and is really useful. I build high end custom built-in cabinets and I use this app to draw the space and then write in the measurements.
The sketches then go to the app Genius Scan and become a part of the customer file.
One thing that would help a lot would be an "undo last" button.
Thanks for a great app!!
