File Panel Extra Columns Enhancement

[rami-shalhoub]

The part you want to Enhancement
the file_panel_extra_columns option in the config file is so useful but we cannot specify which column we want to show

• 0 => Extra columns feature is disabled
• 1 => Also show size column
• 2 => Also show modify date
• 3 => Also show permission column

Instead, it think it should take a list:

• [ ] => Extra columns feature is disabled
• [1] => show size column
• [1,2] => show size & modify date columns
• [1,3] => show size & permission columns
  ⋮

Why it is necessary to enhancement
it gives more flexibility to customise the preview

Additional context
i think also if there should be a shortcut to enable/disable the column feature this also comes in handy when working with multiple open tabs or the filename is long and it is being cut off by the other columns

It was just a feature toggle fore multicolumn mode MVP by design. @yorukot what do you think about this type of multicolumn setting:

may be better use column names instead of digits? like ["name", "permissions", "size"] or ["N", "S"]

"i think also if there should be a shortcut to enable/disable the column feature this also comes in handy when working with multiple open tabs or the filename is long and it is being cut off by the other columns"
here?

[yorukot]

I think using column names directly would be better than numbers.

file_panel_extra_columns = ["size", "modified", "permission"]

This would be more readable and easier to extend in the future compared to using 1, 2, 3.

@xelavopelk for the shortcut I meant a keyboard shortcut, my bad
something like ctrl+i (i for information) to toggle the extra columns on/off
