A couple of things that I think should be added to the Treeview:

- Firstly, the ability to modify the colours. If you don't use a White background on other mIRC windows the white background on the Treeview can become very hard on the eyes (especially if you have a black background normally) not to mention the fact that it looks completely out of place.

- Secondly, if you have a channel or window that exceeds the text limit viewable (for example a long filename on a DCC Send/Get), you can't view the rest of the window name at all, it just goes off and even if you hover over the window it doesn't pop up with a message saying what the window is.
