I love this! It does what it should and there's no annoying graphis or banners or whatever. It's simple enough that I could have written itself, but why re-invent the wheel? This plugin does the job fine!
One small wish: you can edit what columns are shown using the Panel settings dropdown in the upper right corner. Very good. However, I'd like the log to be more compact, so I'm a bit annoyed that the date cell insists on being three lines (I'd like one line with both date and time) and that you can't show username without showing the avatar and user role. Some settings for this would be appreciated :)
