Titles not aligned in center of window.
Version 4.16.1, revision 3d3669fd.
When aligning the window title to the center of the title bar, the title is aligned relative to the space between excluding the window controls, not the full width of the window.
Examples:
I have created a fork on GitHub where I have fixed the issue. This adds a checkbox to the Window Manager settings window, underneath the Title Alignment dropdown, that allows the user to choose whether the title is aligned relative to the window width of empty space.
I was going to fork the repository here and submit a merge request, but didn't have permission to fork.
