It would be really useful to be able to also have a window view (as the one showing the projects and files) with a list of opened files (as the "Opened Document List").
Other alternative is to add a "SHOW ONLY OPENED DOCUMENTS" option to the right-click menu over the "Project Window" which will hide all files, dirs and projects that are not being used.
In either way, the idea is to be able to jump quickly from document to document when you have so many files opened. Going through the "Opened Document List" is sometimes very slow as I have to:
1) click on the "pull-down" button to display the list
2) locate the file
3) click on it
If I wanted to see something and just go back again to the file I was working on, I have to repeat the previous 3 steps. This is when the tabs are not together or are off-screen. I'm using a resolution of 1920x1200 and still I have this problem many times.
Using the "project window" to achieve that task is better but sometimes I have several projects opened at the same time and with several directories (some opened). In order to jump from one file to another I have to scroll down or close directories which makes it also slow.
Having the list of opened documents as a window will let me jump from those files with click of distance (easier if it highlight the current open document).
Another different way to solve it is to be able to have multi-row tabs. Something like "Tab Mix Plus" plugin for firefox. But IMHO any of the previous 2 options is prettier and easy to implement.
Notice that there is now an upcoming feature (outlined in http://netbeans.org/bugzilla/show_bug.cgi?id=172512) that allows you to "kind of" have such a list, see the "Multi-row tabs, with 'right' tab placement" screenshot on http://blogs.oracle.com/geertjan/entry/upcoming_netbeans_feature_multi_row
Have a look at the file switcher in NB 7.2. It is activated by CTRL-TAB.
FYI: There is also the Expose-Plugin http://plugins.netbeans.org/plugin/11826/nbexpose
IMHO this is no P1. Reset to default P3
