Maximus GNOME Shell Extension
The Maximus GNOME Shell Extension attempts to emulate the Maximus package for the Ubuntu Netbook Remix.
That is, it removes decoration (i.e. the title bar) from maximised windows, saving vertical real estate. For example, Google Chrome does this by default. Useful for netbooks with small screens.
|With Maximus||Without Maximus|
NOTE: with the titlebar of a window hidden, you may find it difficult to unmaximise/move a window. In this case, I recommend either remembering your system's keyboard shortcut for un/maximising a window (e.g. Alt+F10 on Fedora), or use the Window Options GNOME shell extension which adds a drop-down menu to the title bar in the top panel with these options (shameless plug, I wrote that one). You might also like the Window Buttons extension which adds the close, minimize, maximize buttons to the top panel.

By default, only fully-maximised windows are undecorated.
If you also want to undecorate half-maximised windows, edit the line in
extension.js to change this line:
const undecorateHalfMaximised = false;
to this (change the
const undecorateHalfMaximised = true;
Blacklists and whitelists
From dev-version 1.3 onwards (v4 on e.g.o), there is support for a window blacklist/whitelist.
If a window is on the blacklist, then all windows except those in the blacklist will be affected by Maximus. If a window is on the whtielist, then only the windows in the whitelist will be affected by Maximus.
To set whether the list is a blacklist or whitelist, modify this line at the top of
/*** Whitelists/blacklists ***/ const BLACKLIST = true; // if it's a white list, change this to FALSE
To add apps to the blacklist or whitelist, add them to the
APP_LIST variable in
You have to add the window's application name (like 'thunderbird.desktop') for it to work.
To see what an application's window manager class is, open up an instance of it.
