Panda allows you to quickly edit small text snippets on your clipboard such as links or tweets. Instead of Copy/Paste, Copy/Panda/Paste like this:
CMD-C (Copy a text snippet to your clipboard)
ALT-SPACE (Open Panda & edit your text snippet)
CMD-P (Paste your text snippet wherever you need it.)
The Panda text editor always opens with the last text you copied to your clipboard. No need to save, when you hide the editor your text is ready to be pasted.
