It would be very useful to be able to create our own templates for items visuals. Obviously not everyone will use the preformated items colour, sizes and so on. The only way what we can do is to manually enter all this property into one item and if we want to use the same item somewhere else we can only copy and paste the item.
However if we want to change an item property later ( for example Fill Color) in multiple items we have to do it in all items one by one.
It would be much more easier to create template for example "button_save_template" and simply link it with all my save buttons in my app so every visual property is automatically set. Obviously if I change something in that template then it will be changed in all my buttons.
