It’s really a great PITA to edit widgets that are partially or totally overlapping. for instance when you have a border and subordinate a slider, its impossible to click on the border to drag it with the slider. You always hit the slider and drag it out which automatically disconnects it from it’s parent.
When clicking on the border in the hierarchy view, its a hit and miss game to go back and click on the green line to actually drag the border. In 90% of the time you click in the slider and mess up the selection.
Also, when you have widgets in a canvas, often you click the canvas per accident and then drag it around and have to go through undo.
It would be good if a widget could be frozen like in 3DS so that it can not be selected anymore
Another major improvement would be if two or more selected widgets could be aligned right, left, top or bottom as well as made to be of equal size
