Some indication that MM13 'is doing something' as in MM11 when 'auto adjusting columns' is displayed.
Never sure when displaying a large amount of info if anything is happening!
Can you please let us know a little more about this feature request?
Which specific command/task do you refer to when you write "when 'auto adjusting columns' is displayed." ?
Apologies, this requirement seems to be covered very well with the 'revolving magenta carousel'.
