In general, I find the reading and marking of messages very good and clear...with 1 exception. 
When I click on an "Info" level message I get a blue background with white text. If I click on and "Fatal, Error, Warning, or Debug" level message I get the same highlighting, blue background with white text. When going through the file I often find myself searching the text or Level column to confirm whether the record I have selected is actually an error level message or Info. I will often click off the record to see the level color and then back on because it's faster than looking for text or level. This is a minor thing...but if you do it 25 times each log, the incremental increase becomes noticeable. The other place I find this annoying is that if the entire message is not visible, such as when part of the cell is at the bottom of the records pane (i.e. only 5 of 10 lines are visible in a cell), when I click on the record, the entire record jumps (scrolls) up so that all lines viewable can be seen. This is fine, but I instantly find myself clicking off/on the record to confirm I'm on the same record and Level.

So, the suggestion here is to use a different color highlighting when the selected record is not an info message. Ideally, this would be different for each level but it would provide instant confirmation of the selected records level without having to re-look at the text or click off/on.
