Open or not open, that is the stupid question.

Here is a power editor called "Sublime", please follow the link to get more information. http://www.sublimetext.com/ Some useful settings: 1. enable vim. In Perferences -> Settings-Default, empty the value of ignored_packages, e.g. "ignored_packages": [], Default ignore the package Vintage, the vim pakcage. 2. default with command mode. Add one line in Perferences -> Settings-User: "vintage_start_in_command_mode": true, The default mode of vintage would be "command mode" 3. tab for 4 spaces. In Perferences -> Settings-Default, modify the value of tab_size with 4, e.g. "tab_size": 4, And also modify the value of translate_tabs_to_spaces with true, e.g. "translate_tabs_to_spaces": true, 4. auto-trim tailing spaces. Add one line in Perferences -> Settings-User: "trim_trailing_white_space_on_save": true, Wish this helps. regards, Stanley Huang
