Change column order

Most reporting tools allow you to change the order of the columns in the "Fields" pane. Power BI seems to put calculations, then table fields and then other columns.
For self reporting it is very important that we can set the order of the columns. Even better would be the ability to organise them in folders.
The easiest way to archive this would be to respect the order of the columns in the Query. The PowerQuery editor allows you to edit the order, therefore I don't know why this is not respected.
A better solution would be to allow the columns to be reoganised and moved to folders in the Dataset.
This was probably the first feature I found missing first time I tried the tool.
