Consider a scenario like this : 

I have a node (let say this is node1) and under node1 i have many node ( this is node2). In node2 there are 12 tabs and each tabs contain average of 10 property. ( rich text editor, image , etc)

Every time node2 is clicked to open, it began to slow. Is there any way to optimize this ? If i re-structure the node let say i create another node ( call this node3) and move 6 tab from node2 to node3, question is, is this the best way to optimize or anyone had through this and have best solution ?

Question 2. How if there is already data selected or inputed in the properties inside the tab we want to move, how can we move the data ? is it create code to move all or there is other way more simple ?
