Cannot distinguish long file/directory names

So would you like to have the font size shrinked until it fits?

Short answer: Yes.

Long answer: I'm really happy with the possibility to view my software projects in Textastic, my iPad's primary choice.
Each project constitute of long naming, like: 'com.mycompany.app.data.sql.persistence.version2.test.java'.
When filenames or directories differ only a very short part of it, I cannot distinguish between them anymore. So guessing is the only option.
My request is to please make it possible to toggle name viewing font size in the dir/filelist pane, either by shrinking or by extending the pane-size.
