I've came up with this rules file, from what I see so far the ! rule should be returned as white-list by externalAppRuleParser.Switchy.parseAndCompile which is not happening at the moment.

Current Status

1. Import Rule (with AutoProxy file)  doesn't work functionally.  The parsed [rules object](https://github.com/salarcode/SmartProxy/blob/dd1cb0629fb6bb0316407e14e31bed30829a1a71/src/lib/RuleImporter.ts#L213) couldn't be [de-serialized](https://github.com/salarcode/SmartProxy/blob/dd1cb0629fb6bb0316407e14e31bed30829a1a71/src/ui/code/settingsPage.ts#L1672)  to [ProxyRule](https://github.com/salarcode/SmartProxy/blob/dd1cb0629fb6bb0316407e14e31bed30829a1a71/src/core/definitions.ts#L729) class.

2. Subscribe rule list to SwitchOmega: it ignores "!" mark (means DIRECT) , which have the opposite effect.

3. Some SwitchyOmega condition cause parsing error:   it requires U2 (uglify ast)
     to compile which we are not bundled. So these conditions should be filtered out.
     (For example FalseCondition (Disableld) , BypassCondition etc ... )

Design:

* We could unify some functions of the `Import rule with file` and `Subscribe rule list` .
  
  * Use same parser for one format , but different converter to ProxyRule  or SubscriptionProxyRule

* SwitchyOmega has 2 formats of exported file (and 1 format of backup file)
  
  * transitional:   without "@with result" mark ,
    
    * we should handle "!" correctly
    * we should show a window asking user all these rulse should use which proxy ( default/active/ or others)
  * modern: with  "@with result" mark ,
    
    * we should handle "+direct" correctly
    * we should either give up all the proxy servers and show a window asking user all these rulse should use which proxy ( default/active/ or others)
    * **OR** we should gather all proxy servers in the file and show a window let user define the mapping between original proxies in file to proxies (default/active/or others) in smartproxy .
    * backup files:
      
      * we might also support import `profiles`
