This script can be run from the script menuextra, or also as an app or droplet if saved as a app. Has not been tested for use beyond OS X 10.6.8 (not sure which useless, silly nickname this version has – still cats at this point, though – I’ve never seen the point in memorizing that garbage).

What it does is ask for files, or as an app use files dropped onto it, as sources to create symbolic link targets at a folder of the users choosing.

Including a non-generic (or less generic) icon since it’s nice to have one when these sorts of droplets are placed in the toolbar of Finder windows. To place in the app package, right click (control click) on the application in the Finder and select “Show package contents” from the pop-up menu. In that window navigate to Contents:Resources, duplicate the original icon file (droplet.icns), and then place the unzipped version of the below icon file into the Resources folder.

droplet.icns
FYI, I did not do a 512 pixel version. [UPDATE] New sexier icon, created with Affinity Photo (and Icon Composer of course).
[UPDATE] New sexier script. Will either prompt for source files or run on items selected in the Finder. Also logs symlinks created.

Logs date, time, and path of symlinks created into ~/Library/Logs/symlinker.log
Not that I've ever hit a return button without being certain of where I was at.
This log does not have a rotation mechanism. Could be added to the periodicals, though.

There is a 'behavior' setting below.

It should be noted that dropping a large amount of files and attempting to link into their
source directory will result in an equally large amount of error dialogs unless user cancels.
You could move the target check to before the repeat, but then you need another
repeat that does the same as in the repeat already here, so *meh*.

-- This setting decides the initial behavior of this script. Set to either "auto" or "prompt"
-- auto - One less step, but your Finder skills need to be up top. Runs immediately on items selected in the Finder where ever it has focus. It is also the only way this script (in its current form) will symlink a directory.
-- prompt - Safer due to having the extra step of choosing in script which files to run on.
