@seco: Remember that this is an Open Source project. Everyone is contributing in a way, even small almost unnoticeable changes play their part. Rather discuss the topic at hand in a positive constructive way. It is fine to disagree, but ditching an idea because you see it as a "hack" or "trail and error" is not helping.Settings are already built-in in MP GUI, we should put effort on that and not add hacks to simplify some trial and error use cases..
I agree that settings are part of the GUI but it is in its infant stages. If we don't use the build in TV, Video and Image plugins there is not much settings in the GUI we can use, since a lot of plugins still relies the windows forms way of settings (I'm specifically thinking of MovingPictures & TV-Series, MoPic has intergrated it's importer into the GUI, but not all settings). So untill then, we will constantly be switching back and forth between GUI and Config.
I believe azzuro just tried his hand at adding this option, and in no way are you required to accept his patch. If you have time then point out his faults like tourettes has, and he can understand the reason why his patch is not up to standard, and improve. If you don't have the time, then just leave it.
I for instance don't have the in-depth knowledge required to start working on the MePo GUI side of things. But I can make patches to the config, because it is more "familiar" grounds for me. So even if this feature would only benefit 5% of the Community then that is 5% more happy people.
