It clearly does make a difference if you, like Jorge, support and comment.
He left a few suggestions for future versions of the MARunScheduler on the official page and that triggered me into to adding one of his suggestions.
So now there is a small update to the MARunScheduler. The update (version 18.104.22.168) includes options to specify which weekdays a thread or an item should be active. Also, a little bug on Clear Run History was fixed.
And please, consider following Jorge' example and share your thoughts on the product. You can see more on how to support this product on the official page and get your copy of latest version of MARunScheduler.
