Quick close of opened files from drop down list

[Fourth of a series of suggestions from a long time NetBeans cnd user]

Both Creator and Netbeans have dropdown lists of opened files.

Netbeans has the additional feature of having an 'X' at the right of the list item, allowing that file to be closed from the dropdown.

In Creator I either have to switch to the file I want to close then click on the X or hit crtl-w, or else switch to the 'Open Documents' pane and close from there. 'Open Documents' almost does what I want, but it isn't always there (I usually have Projects and Outline as my panes on the left), unlike the dropdown list.
