All image viewers i've ever seen have something on screen other than the image they're displaying. I didn't like that, so, pViewer was born. And that's why everything in pViewer is done with the right click menu and keyboard shortcuts. I also didn't want to use two different viewers for viewing images and for reading comics, and that's why pViewer have a Manga/Comic mode. This project is written in C#, and uses the .NET Framework 4, which you need to run the software: https://www.microsoft.com/en-us/download/details.aspx?id=17851 I strongly suggest to open and read the Keyboard Shortcuts/Help menu in the software before starting to use it.

CDG Editor is a tool that allows the user to edit the contents of a CDG file (typically extracted from a karaoke disc as mp3+g). v1.3 now supports all CD+G command types. Please note that this is not a Karaoke creation or editing tools (see some of the comments below) - it is for fixing the CDG files that you have where the text is corrupt due to a poor rip from the original CD+G disk. You have to edit individual CD+G tile commands. This tool could be used to change the lyrics of a song for example, but it would be very difficult - that's not its purpose. Thanks for the feedback though. I've installed it on several Windows 7 64bit PCs but haven't tested the installer or the app on Windows 8 yet. Let me know via the support pages if you have problems and I'll see what I can do to help.
