Order in fields pane

Hi,

Within tables, I would hate renaming my fields since they are straightforward for Q&A, formulae, etc.

To find them effectively, the first thing I do after I import new tables is to jump to relationship view, hide all columns I will not use (not only ID/key columns but also very often numbers since I always work with measures, and dates since I work with one global related date table). 

I then group fields into folders and subfolders

but I would love to group tables in folders within the report view...as well as move my date table to top
