# Solution
I have added different colors, alignments, fonts. Maybe, they are not completely the same as they have to be, because it's not written yet in specification exactly which I should use. However, it's not hard to change colors. Also pay attention to property `Focusable`, that was declared in `BrowserItem`. It's used to make StandardPanel not focusable and at the same time give ability to class buttons be click-able.
There are several things that need to be done for this XAML file:

1. Most big ```Binding``` in this file should be taken out into a separate ```<Binding>``` tag (see below for an example). Of course smaller ```Binding``` statement like ```{Binding Path=CreateMembers}``` does not need to be turned into a ```<Binding>``` tag by itself.

2. There are tabs in this file (line #180), we should ```CTRL+K+D``` to format the entire ```XAML``` file since we are the only ones who work on this file right now.
