2: 1 click load
3: 1 click copy.
4:snippet preview window(can edit as well) also keeps proper formatting when pasting into the preview window.
5: Proper Copy(So you don't have to fight Mono with pasting issues).
6: Drop Down Menu with all your snippets.
7: Delete snippet button.
8: Uninstall Preservation (Keeps them even when uninstalling Unity for a new version of Unity).
9: COMPLETELY OPEN SOURCE! No hidden DLL Code.
Snippet Manager is very lightweight and powerful for what it is with it's preservation safety so you never have to worry about snippet loss when changing Unity versions.
And best of all, as long as this Editor Extension is in your project it will automatically find the snippets so syncing across projects is seamless without even pressing a button!
