[Alexey-T]

I set this and still no deflt conn, plugins asks it

{
    "connections": {
           "MySql": {         // Connection name, used in menu (Display name)
              "database" : "my_tst",
              "host"     : "localhost",
              "port"     : "3306",
              "type"     : "mysql",    // SGDB to use: (mysql, pgsql, oracle, vertica)
              "username" : "root",
              "password" : "dd",        // (if you are using postgresql, you must setup a pgpass file and set it to null)
              "encoding" : null        // Your DB encodings. Default: utf-8
          }
    },
    "default": "MySql"
}
