Sometimes is really difficult to move the size of a column due to the elements inside. It would be amazing if in the column settings (for the top row) could put 50-50 or 70-30 and so on the sizing for the type of column. if there is a 3 column 34-33-33 and so on, instead of just using the blue line inside the column that sometimes is impossible to move due to it changes.

Or at least if you press a key it stays on the row instead of moving to the elements inside...

Any of those work for me. :)
