in adding inputs,
make the last type input added the default when adding more inputs.

make drag and drop a common way to add inputs.
it works for photos, and should work for folders.
if the folder is images, than images is the type of input.
if the folder is videos, then video list is the input type.

add drag and drop images folder, so I can drag folders of images onto the input list.
images folders should default to the last times and transition last used for such folders.
