@hebasto - here is a barebones fix for #191
We can tweak the presentation in a follow up PR.

Thanks for fixing!

1. Did you find out the reason of head flickering?
2. Could using of GUIUtil::TableViewLastColumnResizingFixer be a better option as it is used in other places of the GUI?
3. Do you mind dropping @ from the PR description?

This PR does not fix #191

It instead creates a new column in the Peer Table model. A fix to this should not hack on a new column so that the User Agent column does not glitch. Perhaps a refactor that creates a PeerTableModelView which makes use of TableViewLastColumnResizingFixer is more appropriate.

@jarolrod - It sounds like you have the motivation to implement a proper solution.
I will be excited to see how you refactor this into a proper MVC implementation.
I will be ecstatic to see it actually get merged!
Happy coding!

@RandyMcMillan was just relaying what I found while reviewing the PR. Wasn't trying to discourage you in anyway or come off as rude.
