[Suggestion] A few improvements

[Pegoth]

I looked at the code and I recommend a code cleanup with ReSharper. And I noticed that you saved Top as X and Left as Y in the settings. It should be the other way around (At MainWindow.xaml.cs line 488).

Settings.Default.WindowLocation = new System.Drawing.Point((int)this.Top, (int)this.Left);

Overall I like the program, but found a few possible improvements:

Smaller improvements

• [x] Pop up the settings window on first start instead of the dialog box
• [x] Browse button for the Client.txt selection in settings (Microsoft.Win32.OpenFileDialog)
• [x] When buying item make the stash button non-clickable (preventing the "is it a quad stash?" message)
• [x] When the game not in foreground hide the visible windows

New features

• [ ] Option to grow upwards (to make it possible to place the window on the bottom right)

The last one is very tricky, maybe in the near future. Same with hiding.

The last one is hard yes, but the hiding is not at all. I threw together some 10sec coding.

[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();

private void tick(object sender, EventArgs e)
{
    if (GetForegroundWindow() != FindWindow("POEWindowClass", "Path of Exile"))
        Hide();
    else
        Show();
}

private void starttimer()
{
    System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
    dispatcherTimer.Tick += tick;
    dispatcherTimer.Interval = new TimeSpan(0, 0, 1);
    dispatcherTimer.Start();
}

Is now implemented :)
