It would be really useful to have 2D editable text tools.

If you need 2D text in Blender for your textures you need to rely on external tools like Gimp or Photoshop. Because of the extra steps you need to take this workflow is prone to error. Text and text corrections are always a sensitive subject for clients, when you make a text error its always an eyesore that you just need to correct.

* There is of course the workaround method of creating a new scene with a camera and adding Blenders built-in 3D text and rendering it to an image but this is cumbersome. At specially if you have a lot of textures with text in them.
