Hello. 
Edit: Save the script as an application, that doesn’t stay open, and displays no opening screen.
It should be named Crt.App, and dragged to your Finders toolbar. When clicked upon it will open a window there, with the current path of the Finder window as its current directory.
It will open a tab, or use an unused tab, in an existing Terminal window if such exists.
You can also drag Finder items onto it, several, and have them open in separate tabs, with the current directory set to the folder, if it is a folder, or the folder containing the file, if it is a file.
I use this, having set up Terminal.app to be shared among all spaces, and will then have no more windows, than I opt for.
The feature of reusing tabs works best with the accompanying prompt file, which is to be sourced from your .bashrc file. This gives you easy access to history numbers when you want to re-execute commands.
Then you can just enter ! 2 (enter) to rexecute command #2 and so on.
Tt is also necessarey to make the number of words in the window’s/tab’s command history predictable, as that is the parameter for checking if the terminal window is unused: hit cmd-K, when you are done with a tab, and you are ready to reuse it. This gives you the benefit of having your previous command history there.

I owe a lot to Nik who set me onto the idea, and Marc Linayage, who's script served as the foundation for this,
though there is nothing left here.

Crt for Snow leopard and later. To be installed on finders toolbar.
Makes a new tab in current terminal window or creates a new window if none available, i.e terminal not running
reuses a tab if one is unused.
This applet works best if you have terminal set up to be active in all spaces, in the "Spaces and Expose Preference pane".

Dropping files onto it on the toolbar, in order to change to that directory works too, great when having a spotlight window up.
Save it as an applet, and it deserves a nice Icon!
No Copyright, as I have used others works so extensively, and no warranties what so ever. But please, have the decency to
refer to this post at Macscripter.net, or My upcoming github repository (with icon there!) (http://macscripter.net/viewtopic.php?id=39017)

The prompsetup file that are to be sourced from your ~/.bashrc file:
[code]#! /bin/bash
This file is to be sourced in your .bashrc.
To install promptsetup in your ~/.bashrc; insert
this: “source ~/.init/promptsetup” The current
promptcolor is set to black to set other colors for
your prompts: http://linuxgazette.net/issue65/padala.html
The number for black (30) is the only you should have to
replace, if you can accept to have the prompt
towards the background of your terminal window.
