This options is there - choose "Search & Replace" and set action to "Replace all matches" on the target tab.

Though we consider to add a menu item that does this automatically.

Oh please do! Search&Replace using anjuta is horrible and time consuming!

Adds a "Replace All" Button to the Search-Replace Window.

Attached a patch that adds a "Replace-All" Button even when in "Replace next match" mode. (Haven't removed the old "Replace All" mode from "Search Action" combo-box).

Review of attachment 157832 [details] [review]:

Looks ok overall. I mean, search is horribly broken anyway and this patch cannot fix it but it probably makes things a little bit better.

Any reason to use a temporary variable here.

There is a replace all now in the inline search, that should be fine.
