Now, instead if you want to hide the easy-setup button, do this:
Create a folder named "Hide Easy Setup". In it, put the following files:
display: none !important;
"name" : "Hide Easy-Setup",
"version" : "0.1",
"description" : "Hide Easy-Setup",
Then, modify Opera's shortcut to launcher.exe so that the command is like this:
"C:\Program Files\Opera\launcher.exe" --extensions-on-chrome-urls=true
Then, load the unpacked extension (see previous post for how). Just note that if Opera is ever launched without --extensions-on-chrome-urls=true, Opera will remove the extension on you and you'll have to load Opera again with that option and then load the unpacked extension again.
Then, the speeddial page will be white AND empty.
I think if there was an option to hide the easy-setup button and make the whole startpage white, that'd help a lot.
