Just to let you know that we are already working for some time on a brand new design view and Monaco code view synchronization.
It is a complete rebuild of the whole UI properties editing and synchronized code and design. With code as being the primary source of truth.
We are finalizing the new engine now and hope to give you a preview this or next week so you can try it out.
One thing is for sure - it is a giant step forward with mighty synchronization speed (real- time) and a rock solid editing.
So all problems like this one will be solved.
But we need to test it well first so we will be releasing it as experimental feature first for you to try it out and give us your feedback.
