I wish i can group multiple elements to move or resize them together. Adding an option to add a grid and arrow keys can also be helpful.
The current alignment guides don't work to guide you to the universal center of the screen but rather aligns your current element with the other existing ones. If you kept on resizing the already existing elements, esp the one that served as your guide to the center and that went off-center, the succeeding elements that you add will follow the wrong centerline like in my case where i only noticed very slight misalignment of all the elements after everything seemed to be in intended place that i had to select them one by one and carefully move them to the left. It would have been such a breeze if there were a selection tool (or lasso) that lets me encircle everything or smaller groups of elements to make one bigger element.
