I thought I’d ask this question early. I tried changing the .php extension on some files that EE made for me. I changed them to .css and .html where it was appropriate and it doesn’t seem to make any difference to EE. This certainly makes other things easier for me in other ways, such as opening my editors. Will this make any difference later on as I add more and more files? Um obviously I’m saving all of my files as text files and editing them with an external editor.
