This is the best application of its kind.
The ability to use different regex engines is fantastic.

Just one request:
I'd really love to be able to use this app entirely from the keyboard.

I don't need it, so I don't care, but I can't figure out how to use the new replace function...

Feature Requests:

- Ability to delete the log
- Menu Items (so that I can press a Keyboard shortcut instead of using the Toolbar)

I can't seem to be able to open the .dmg. It says something like "unrecognized format" (freely translated from Swedish to English).
