Say if I am on line 8491 (displaying all lines). When I go to click Show only highlighted item, I go to line 16777. I imagine the program is staying at the correct row count per each view mode (all vs highlighted)... but if I'm on line 8491, then when I highlight, I expect that part of the log to display on the screen.

My use case is that I have errors highlighted... but If I want more context, I unhighlight the log. When I unhighlight and go to all lines, I'm taking to a totally different place on the log.

I see what you mean. I am scrolling with my mouse or using the scroll bar. So, the row selected is off the screen... Yeah, I can see how there's a pro and con to having it one or the other. I guess my choice is to use page down over scroll mouse or scroll bar.
