Hi Tamil
Congratulations by this blog, it has very useful information for whole opera users.

I have a blog: http://my.opera.com/el_esponjoso/blog/ in spanish, I had translated almost all your posts but this post will be very difficult for me writing it because the information is on a table and I don`t know how to put information in tables in posts of My Opera blogs,

so I ask you, (if only you want or wish), please sending me by PM the source code of this post for facilitating me the writing of this post in spanish.

Cheers.
:wink: :wink: :wink:

Addressbar Content Search - Enable address bar content search
Visited Pages - Enables content search

Those two could be clearer.

Addressbar Content Search - Determines whether to search the contents of the database in the addressbar.
Visited Pages - Controls whether full-page content should be indexed or not.

Great tips ! :)

Is it possible to have the IS ID to change the string instead of just added a substring ?
It doesn't really spoof the id, it just add another string to the first...

Hi Tamil,
Thanks for your info. It Is a very interesting blog.
I would like to ask your help, for a problem I have. Using version 9.51, I cannot keep the entered addresses. For me it is very useful, the addresses to be kept and to be reused without entered words.
Thanks in advance.
Kostas.

You should not replace default dialog.ini with my dialog.ini file as it contains only modifications. See the instructions in More color schemes in Opera.
