Re: Further simplicity and ease of use...
It used to be a pet peeve of mine that every GNOME app used to start with a G and every KDE app would start with a K, e.g. gcalc, konqueror etc. and it took a long time for them to realise how stupid that was.
Fortunately some usability has seeped into desktop Linux since then.
But I wouldn't ever rename GIMP "Photo editor" because it's way, way, way too complex for that purpose. There should be an explicit photo editor that lets someone fix red eye, crop, frame, filter etc. from a simple user interface. Let people discover GIMP if they outgrow the simpler tool.
