For the final time, I KNOW that the target title selector doesn't work, YES I WILL add folder support, and YES I WILL release the source code, when it's done and not before. This has been answered several times before yet I'm still receiving posts in this thread and conversations started about these issues. I will not be answering these questions again as the answer is unchanged. Sorry if this comes across as argumentative but it's frustrating to be badgered with the same questions over and over again when they have already been answered. Asking again will not change the answer.
WRT the bar at the top - it is mostly for information but I now realise that this information could go on the top screen (e.g. A settings logo). I'll consider removing it or making it optional.
As for folders, I haven't got my head around how to code folders within the grid yet (I.e. how it works on the home menu). The initial implementation will probably involve tapping on the top bar and selecting which folder you want to view, and the whole grid will then change to display that folder. Folders as an icon within the main grid might come later but is not a priority.
