use [WXGlade](https://github.com/wxGlade/wxGlade) to build lionGui.wxg: open the file in WXGlade and press file\generate code. LionGui.py will be placed in the addon\globalPlugins folder. Please modify the GUI only using WXGlade. Then, just zip the contents of the addon folder and chage the extension to nvda-addon.
