It is possible to Hide Pages in Your Watchlist using CSS. To hide a page, go to your skin.css page. The CSS code required is different depending on whether you have the "Enhanced recent changes" option selected in your preferences.

Shortcut WP:HIDEPAGES

Use the following example to hide whatever page you want from your watchlist, by adding a line (on a new line) in your skin.css page file. Example:

.watchlist-4-Hide_Pages_in_Watchlist { display: none; }

hides Wikipedia:Hide Pages in Watchlist.

The "<nowiki>4</nowiki>" is the namespace of the page, which can be determined by using the table found on the right of this page. Spaces, slashes (<nowiki>/</nowiki>), apostrophes (<nowiki>'</nowiki>) and some other special characters must be replaced with an underscore (<nowiki>_</nowiki>). Some characters like parentheses must just be omitted. The HTML source of the watchlist will show the required name if the page is present on the watchlist.

Another example:

.watchlist-5-Manual_of_Style_Layout { display: none; }

hides Wikipedia talk:Manual of Style/Layout.

When using "enhanced recent changes", the code for the above examples is changed to:

.mw-changeslist-ns4-Hide_Pages_in_Watchlist { display: none; }
.mw-changeslist-ns5-Administrators_Noticeboard { display: none; }

Note: the previous script method for doing this is now deprecated, and didn't work with "Enhanced recent changes" at all.
