It would be great if nova had auto rename paired HTML/XML tag, similar to Auto Rename Tag - Visual Studio Marketplace
Where you change < h1> for example to h2 and changes automatically
Also the ability to copy/paste files and folders in the file browser
I think there’s a few extensions that do this already
Ash thanks for the response, r u sure? I haven’t seen it, but I do believe it should be a core function, as copy paste files and folders 
I didn’t see the extension, but hopefully Panic sees this, Auto rename closing tag is something even codepen does, for example: if I change < h1 to h2, then get updated automatically
I don’t see an extension either. And I agree it should be part of core functionality. Nova is already going through the trouble of detecting the closing tag—if you put your cursor in the tag name (don’t select the tag name, just have the cursor blinking in the tag name) then the editor provides a soft highlight/tint of the tag name for both the opening and closing tag. They’ve essentially already done the hard work figuring out the matching parts. Then they could just add a keyboard shortcut that would select both of those instances to allow an edit to happen.
Seems so simple yet, it missing, also copy/paste files/folders
There is an extension called Tag Sync that works the same way.
