Well, The GUI is more or less the same that when I started to use this bot long time ago and I don't see why it is confusing. This app is similar to other apps: we need a config button to configure it, a play, pause and stop button, and the bot has all of them.
IMHO, options are easy to understand, but I will agree with job list that is a bit annoing (and IMHO must be changed), but the rest is OK under my point of view.
And of course, the bot does the job, and that is the best part.
I had problems configuring my bot too. I know how to fix some problems reported in the forum because I faced them, but all apps need a time to know them and understand how they works.
