I appreciate to finding the new version Webstorm 7.0 integrates terminal into IDE. It's awesome and useful for web developers. I used to execute two powershell windows for implementing workflow and chrome autosave, and I only need webstorm now. By the way autosave command needn't execute if you choose the correct file in Sources pannel of devtool in Chrome.
I'm thinking to change my IDE to sublime text 2 in these days but found it's hard to find my feet on the new IDE. Now all problems are resolved. I'll go on working by webstorm with pleasure.
