I would love to be able to target an application (such as chrome with a youtube playlist open) and send command based off a regexp. For example when youtube changes video the name of the process changes so I can't consistently target the same window as VA currently is. Now there is the issue of multiple matches. That could either throw an error/warning to the user saying multiple processes match the give expression or trigger in all of them or just the first match. That would be up to you(maybe even configurable options).
