One thing that I love about KfW is the selective editing: You can specify a target pattern and view only those lines that contain that pattern; you can then edit them as a block or toggle back and forth instantly between full and restricted views.
EditPadPro has already been mentioned a number of times in this thread, and this is yet another thing it can do. Ctrl+F to open the search panel, enter your search pattern and press enter. Then click the "Fold" button to see only the lines containing your pattern. You can still edit the lines when folded, and unfold at any time. There's also a Highlight button to color-code the matches. (Keyboard shortcuts can be assigned to all these functions.)
You can also restrict edits to within vertical columns or inside rectangular blocks, overlay and fill blocks, etc.
EditPad Pro does have rectangular selection (an option under the Block menu), but it doesn't restrict editing to the marked area. Typing inside a rectangular block will replace the selection, which usualy produces something of a mayhem.
Em Editor does a little better with rectangular selection: whatever you type in one will be repeated in all selected lines. Useful e.g. to prepend a comment character to several lines. But Em Editor doesn't fold the text to show only matching lines.
