Do not auto-adjust column width
I've been using Gnumeric for decades and it's my favourite spreadsheet, except for one lone issue that irritates me tremendously. When entering a numeric non-integer value in a cell, whose column width has not previously been set manually, Gnumeric immediately expands the column width to show 18 decimals of the number. Please, please, please, please, please, please, please, please, please, please, please, please, please, please, please, PLEASE, please give me an option for it NOT to do this. I've spent countless cumulative hours re-adjusting column widths.
