customize format of MultiFileChooser as list

[mbassiouny33]

Hi there,

Thanks a lot for this great tool!

The multifilechooser is nice and supports drag and drop, but the format does not intuitively indicate that it supports drag and drop.

Also, it is not practical when dealing with a list of files

Examples of impractical cases:

• if the user added several files and wants to double check what they added,
• add 1 file after another from different directories.
• Add several files, then maybe remove one of the files.

Example of a practical list of files

• You can DnD or use the add which acts like the multifilechooser. And the user can pick an item from the list and click remove
  

Or even something more elaborate with columns, or arrows to select an item and move it up and down in the list

is there any way to customize it and enrich it on my side?

or does really require modification of the core code of Gooey/creating a new widget type? if so, I would really support this feature request with a donation

Thanks
