Today's update is all about whitespace. I've created a new textbox control for Regex Hero which is now being used for the 4 main textboxes: Regular Expression, Replacement String, Target String, and Final String. The new features are as follows: Figure 1: Matching Line Feeds Handles tab characters as it should. You can test this by entering \t in your regular expression and then hitting tab in your target string. Matching carriage returns or line feeds are now visible with a half-width character block (as seen in the figure 1). You may preserve the formatting of pasted text with the new "Preserve pasted formatting" option. This will retain the existing line endings of your source text as was suggested about a month ago. Cycling through your matches with the up & down buttons is now much more responsive.
