I know this has been posted many times, but here goes:
13.04 and lower - could unlock a launcher from the unity menu bar, then open the menu and drag a launcher to the desktop.
No go in 13.10.
It was posted we should use the file explorer, locate the given app, then copy the thing to the desktop. I've been able to do this with a few things, but it is way more time consuming. I just now spent over 30 minutes just trying to place the various LibreOffice subproducts on my desktop, to no avail. I tried every dang thing I could. After 25 minutes I found the launchers. Copied them to my desktop - Ubuntu won't run them and gives me an error about untrusted launchers. Really????
Take a hint from Mint - allow right-clicking a menu item and saying place on desktop. Yeah, sounds like Windows too, but you know - if it works, why screw with it?
"Someone" has taken away a very simple thing and made it difficult at best, impossible more likely, to create desktop launchers that have the same icons, etc.. We should not have to add a launcher, set the string to what it is to execute and with conditionals like document name, then go hunt up an icon and change the launcher for it.
I'm pretty much stuck right now on using 13.10, but I *HATE* not being able to simply move a launcher to the desktop. It's wrong. Security issue? How?
