Just FYI, I downloaded EditPad Lite, and I like it a lot. Thanks for reminding me about it Garlaen!
My favorite features are the ability to set file associations from within the program, and the ability to have multiple files open in the same window, with tabs at the top for quickly switching between them. Not to mention it runs in the system tray, saving valuable space on my taskbar!
My favorite by far though, is the search and replace function. Takes a lot of the monotony out of changing the graphics/dimensions for a particular element (gauges especially).
