not what you’ve asked for, but here’s an Apple tip that might make this easier for you:
do you know about App switching with Apple Tab?
hold Apple, hit the Tab key
you get a display of all your open apps
keep hitting Tab till you land on the app you want
release the keys.
ok, so here’s how to make that even better:
with FCP you can easily drag & drop files direct from the finder into it;s browser, (or even timeline if you wanted)
after you copy your file fro the desktop to the new location,
grab it
start to move it away,
Apple Tab FCP into the fg, then drop the new clips into the browser.
cheers,
