Can't see if a space is matched, with the current colouring?

[jsekamane]

If I write a regular expression that should match cat + a space: 'cat ' e.g. cat\s then I am not able to see if the spaces are matched in the Testing string panel. I can only see the count, but not was is actually matched since the text color wouldn't be visible for spaces.

I guess it is the same problem for other hidden characters e.g. \n

Can it be changed from a text color to a text highlight color? Or can there be implemented a "show hidden characters" function like photoshop or word?

And thanks for a great program.
