I use the default Nautilus File Manager to view / manage files.
Is there a way to add icons or customize the icons that are above the location bar and below the menus? There is a bar that has icons for "Back" "Forward" "Parent" above the location bar. I want to add "Delete" so that I can quickly delete selected files. I cannot find a way to add icons there.
On a Mac, in the Finder, one would right click and select 'Customize' to do that. Is there an equivalent in Gnome / Nautilus?
I have to agree with you. The desktop wars are long over. News from the front: Windows won.
Unless there is a spectacular advantage, most users will not switch. The Gnome folks seem to be bent on fighting the desktop war all over without the benefit of billions $ / year in cash flow. There is a very health market for those who know what they want and want to customize to personal preference without the interface getting in the way.
I mostly use Linux just in Bash, I kinda like KDE, but daily I use OS X.
