    Reor 1.4.1 is visually pleasing and feature-rich, but it has a number of irritating bugs or design flaws. A rendering bug is experienced on Windows 7 x64 on Intel Core i5 with Intel HD 2000 graphic subsystem, where using the full-screen menu, invoked by left-clicking "+ Menu" button causes panels to be partially or completely invisible. It is possible to minimize and restore Reor to reveal those panels. To work around this bug, use the alternative menu by right-clicking on "+ Menu" button and never use. Alternatively, invoke panels using keyboard shortcuts. It is not possible to use the shortcut keys as rapidly as it is possible to do so in other apps, such as Microsoft Word. For example, the shortcut for the unit converter is Ctrl+U and for the format toolbox, it is Ctrl+K. However, to invoke both, holding down Ctrl, tapping U and then tapping K does not work! You need to hold Ctrl, tap U, let go of Ctrl, hold Ctrl again, tap K and let go of Ctrl again. Reor always remains on top, does not show itself on the taskbar and minimizes to that cursed area known as "system tray". Its Linq feature is a poor replacement for a proper jump list.
