Clipboard Workspace
What is it?
The clipboard workspace is a special editing window that makes it easy to edit and clean up the contents of the clipboard in an (almost) automatic fashion. Rather than manually pasting in text after a launch or copying it out before you quit the app, the clipboard workspace does this automatically.
You can enable/disable the use of the clipboard workspace via an option in Preferences > General. When disabled, TextSoap will just open an untitled document on launch, much like most document-based apps.
How does it work?
When TextSoap launches, the app creates a window and pastes in the current contents of the clipboard into that window.
You may then edit the text, clean it with any of the existing cleaners, manually find and replace text, and so forth until the text is satisfactory for your needs. While working with your text, you may use the clipboard as normal.
When you quit TextSoap, the app (automatically) copies the contents of the workspace window on the clipboard for you.
Other integration options
The clipboard workspace is great tool when you may need to do more than just apply a cleaner and may need to manipulate the text manually.
If you just need to apply a cleaner to text, you can look at some of the other integration options which simplify the workflow even more.
