Very good explanation, thank you! That's quite right; if I open two files from within the same directory they end up as tabs in the same window, but if I open two files from disparate directories they end up as separate windows.

So what I'm asking for is something like a menu item Open In New Window... so that I can pick a file and have it open in a separate window (rather than having to open the file and _then_ move the tab to a separate window as I'm doing now).

Similarly, it might be nice to have a modifier key such as Shift that I can hold down during a drop onto the TextMate icon and have the file open in a separate window.

I added option (⌥) as a way to force a file to open in its own window (rc.14).

I have noted that people would like to have a preference to set this as the default behavior.
