I think Programmer's Notepad might, but for the life of me, I can't remember.

JEdit has an extension called BufferList that does that. It's my favorite editor, though because it is written in Java the startup time is a bit slow.

I've been customizing JEdit for probably well over an hour today. The "switch buffer" plugin is great too. I noticed PSPad, also an excellent editor, supports a vertical buffer list as well. I'm probably going to wind up switching to JEdit as my main editor, and most likely fall back to PSPad if I don't.

This doesn't mean I'm not still looking for recommendations though!

Kate, the editor that comes with KDE has this, and I believe there is a Windows port. You might have to install the whole of KDE though.

TextPad does have this. I accidentally discovered it a couple days ago when I chose Show All Files (or something to that effect; I'm not near my PC that has TextPad installed on it) from the Window menu.

Yea, TextPad does have it as someone I work with uses it frequently. Ultraedit does also...
View -> View/Lists -> File Tree View
Then hit the dropdown for "Open Files". You can turn off the tabs in the View/Lists menu also.

Just confirming Textpad does this. You can press F11 to turn this on or go to View -> Document Selector.

I just downloaded TextPad to try it out. Does it not let you open files over FTP??

I use NotePad Pro a lot, and it has this. It is darn fast and supports most things you'd expect ... except a file browser pane.

NotePad Pro? Got a link?

Ultraedit can be set to view file lists (vertically). Just go to the View menu, then Views/Lists, then select File Tree View (you can even turn off the Tabs). Or you can just click Ctrl+U.
