File Manager Add Sticky Header and Column Order

Hello, I love the control panel. I am new to using it and would like to contribute by requesting some updates that would greatly improve its available features. Currently the file manager is very good. What I would add to make it excellent would be:

  1. Leave the actions menu fixed and always visible
  2. That the name, size and last modified columns can be sorted
  3. That the files can be edited in a separate tab to edit several at the same time.
