improve file system explorer for file/dir selection or allow user to use a third party one

Its hard to read and not very useful especially for low vision person. If possible find a solution for:

  • Icons, font are too small,
  • colors not well choosen,
  • no preview for pictures,
  • no sorting or searching option
  • no ability to choose number of rows/columns or setting view as a list.

Or allow user to choose favourite file explorer
