1. it's need to set up default size of all creating items on complex screen.
for example, when a create new it is set by default width: 500, height 100.
I need to create 50 graphs on screen, and I have to change size fo 50 times again.

2. If I have more items that can show my TV, i need to resize all items. And it would be great if you add a function like "resize all items on screen to new size (that i will set)"

3. If i have 50 items, graphs, etc.. when i create (modify or delete) those items - the complex screen page is updating every time, and resizing for 3-5-10 sec. It also creates a large load on the server, requesting same data every time. The best way would be this: instead of reloading the page you are loading via AJAX HTML block for creating / editing an item, and thus reduce the server load and increase the process of creation / modification of complex screen
