I assume someone must have submitted a bug report to this effect at some point in the past, but since i haven't heard a single mention of it from anyone in over 6 months i thought i would submit my own:
Could you please add support for showing host names on join/part/quit in the channel log? This is a basic feature that almost every other IRC client i have ever used supports, and it helps greatly in identifying people who are leaving and joining the channel.
configuration: Linkinus 2.1 (and earlier) / Snow Leopard

The single most useful thing you can do when filing a bug report is to include a numbered list of steps that trigger the bug for you every time, like this:
1.) Start the application
2.) Click on the File menu
3.) Choose Print
4.) ... etc ...
Not all bugs are consistently reproducible -- but if your bug is reproducible, and can be reduced to a series of steps like this, it's as good as fixed once an engineer gets hold of it. Engineers love bug reports like this because it eliminates so much guesswork and trial-and-error.
Be meticulous and specific, but try to reduce the problem to the smallest number of steps you can. Say the problem occurs if you open an image, crop it, then save the image. Try eliminating the cropping step and see if the problem remains -- it may not be necessary to trigger the bug.
Sometimes users file bugs against the designed behavior of the program: "When I do X and Y, Z happens!" -- But, as far as the developer is concerned, Z is what is supposed to happen when you do X and Y.
To avoid this, it's best to include "expected" and "actual" results after your list of steps.
