Maybe this should be two seperate requests, but I feel like they should be together.
Request reason (story):
I tried to ask if they existed on Ask Ubuntu (I use lubuntu), but no-one answered, I then asked in other sources, but I found out that these plug-ins do not exist.
Usage: especially on small screens, it would practically combine the top maximized window bar with the system tray/indicators, thus cleaning the bottom panel without using additional screen space.
Plug-in 1 - Window controls:
-only show when there is an active window
-three (or possibly more, based on user settings) buttons that would control the active window - Close, Iconify & Maximize
-settings for buttons skining
Plug-in 2 - Window title:
-show active window title
-if there isn't any active window, show "LXDE Desktop", or any other text based on user settings, or nothing
-settings for font, alignment(, stretching)
