title

Information bar:

Workspaces	Title	Clock

Method

Both

This is the method that being used in Windows OS and most Linux's DE, it's display window's title both attach to the window itself and then show a list of windows on the information bar.

Busy	Tabs

Pro:

This is a legacy design that most people get used to

Con:

The design is too old and outdated, display windows title in two place is redundant and make the desktop cramped

Detach

Only show a list of windows on the information bar.

Busy	Tabs

Pro:

This method give you the biggest screen real estate
And still shows you all the information, this is better than the Attach method in tabs workspace because it can even show extra information (workspaces and clock)

Con:

The problem is the way the information is presented, a list of title can show you how many windows and their name but not their location, so you end up confusing not knowing which title is corresponds to which windows, you can't even tell if the container have tabs or not (You can make a container show title bar if it's has tabs but this is redundant to show title in two place)... This defeat the whole purpose of display title for each window
it's hard for mouse user to interact with a window (drag and move window around)
Those titles can take a lot of space in the information bar, space that can be used to display CPU, MEM, DISK, TEMP...
