Hi!
By right-clicking to lister header we can fast add new columns to lister. But added column is always last in line. Will be good to check mouse hover and place added column between (before) currently hovered column.
Thanks for the suggestion, we'll put it in the list. (I'd like that as well.)
I have had this thread in my "to do" list for a while, but I realised today that this has already been implemented - simply edit the column header context menu, and change the command to Set COLUMNSTOGGLE=columnlist,insert.
