i hope webstorm can auto change project index like this:when i'm in project1 folder,change project index to 0,and when i'm in project2 folder change project index to 1,...,or provide any others feature 

i create webstorm.config.js in order to resolve alias '@' and others my be used 

'use strict'
const {resolve} = require('path')
const project=[
  './project1',
  './project2',
  './project3',
  './project4',

module.exports = {
  context: resolve(__dirname, project),
  resolve: {
    alias: {
      '@': resolve(__dirname,project+'/src'),
    }
  },
}
