I would love it if you copied textmate's soft tabs. I don't want to convert entire files to spaces or tabs and make the file history confusing and/or break other people's indentation that they like. I just want sublime to auto-detect the tab size and when i'm at the beginning of the line and press the left or right arrow key, it should jump over 4 spaces and look like i'm jumping over a tab. Another way to put this is that I would love it if my cursor jumped between TAB guides at the beginning of the line.
Thank you for building a life-changing code editor! My life has been so much easier the last two weeks.
