So to "replace the image", I just re-copied the extracted image that I had saved on my computer HDD, over the existing image on the SD card. That should be a "clean install", yes?
So just to be clear - should I still be seeing an app in EasyDebian's menu list that I installed myself, even after I copied the original extracted image over the current, messed up/modified one on my SD card?
/usr/share/applications
Sorry to be such a dweeb and repeat myself like this ^_^.
Also, about your comment about keeping or losing the audio, I vote to KEEP IT! I am realy looking forward to experimenting with audio and video recording/playing/editing apps on EasyDebian, and it would be a major loss to lose audio completely. Please at least keep available to the users a functioning version of EasyDebian that retains audio!
