At last I found the code explorer that actually works out of the box and is very light!. Thanks
My first suggestion for settings is an option for changing foreground and background colors of the view.
Keep up the good work and Keep It Simple!
Thank you. Foreground and background colors of the view are in the TODO list, however I'm not sure whether it will be included in the next release which is currently under development. My current goal is to fix existing problems and to enable the navigation buttons.
