But the internal editor is really good and quick. I may open ten PHP files from customer's site simultaneously. I keep on searching variable and function names from all those modules all the time when making modifications to code. Then I save the modified PHP with one click to test the code. The work is searching oriented all the time. And no need to download/upload files tens, maybe hundreds of times.

Internal editor with "save using another name" would be the real tool. Then it would be quick to save different versions for testing. For me the internal editor is a treasure in small jobs! :D

Well, you can use any external editor you like that supports these features :)

When there are many documents open in editor, separate FindUp, FindDown, FindAll buttons would be much quicker than Direction Up Dn radio buttons and then Find Next button. Now it takes multiple clicks to search the text from the open document. Time is money! LOL.
