Wow, horrible! I tried to select a few characters and copy and paste but it didn't copy the part I selected. instead it copied everything. Also if you tell me the format is 00:00:00 then I'm going to type digit digit colon digit digit colon digit digit but instead you auto inserted the colon which means now my typing and correcting muscle memory is doesn't match. I typed 8 characters so it should take 8 key presses to backspace or 8 characters to go left. Please don't use these on your site
