How can I accomplish these two scenarios in a popup window "Downloadable Files":
(1) In the file explorer panel in the upper left, have the computer
remember the folder you were in the last time you opened the window during
that session, so that the explorer panel opens to the default location that
is the same as the last time you used the tool. Often I have to upload
several files to the same folder, then I have to insert links to these
files into a web page. If the folder is several subfolders in from
the root directory that is the default, I have to re-browse to it each
time.
(2) Set the "target" property to "New Window" by default (OR, have the
computer remember the properties you set the last time you used the tool).
Usually when downloading files we want to set the target to new window, but
its easy to forget, and you have to set it each time because it doesnt
remember the properties you set on the previous link insertion.
