Tips
Watch CSS for automatic upload with LESS
Many ask why coda does not detect the changes. It detects the changes, but only, when you open the css file once with a right click with 'Open in Coda 2'. Close the file with CMD+W, since we don't need to edit it. After that Coda monitors the file and marks it on changes automatically for upload. This only works in current session, after closing the project and reopening it, you need to do this again.
