-A scrollable tiling window manager tiles windows, but it does not maximize their widths. Instead, it leaves the width of windows to the user's control.
-Windows are automatically centered when possible. And when running out of width, windows can be scrolled through horizontally.
+Karousel works differently from most tiling window managers in that it does not maximize the width
+of windows, as this can be undesirable with wider screens, where it results in excessively wide
+windows that require large return sweeps when reading their content.
+Instead, it leaves the width of windows to the user's control. This additionally prevents
+unprompted reflow of window content.
