🖥 Window management à la Rectangle (+ align all windows at once)

Manage the current apps windows. You can do all window alignments Rectangle has to offer:
max,
almost maximize,
half (left, right),
thirds (left, center, right, left two thirds, right two thirds),
quarters (top-left, top-right, bottom-left, bottom-right),
fourths (horizontally: first, second, third, forth, first three, last three),
sixths (top-left, top-center, top-left, bottom-left, bottom-center, bottom-right),
and move to next screen.
Why another window manager? You can align all windows of the current app at once. This comes in handy every time you work with an additional display or you like to have a clear window structure for an application. On top, you can easily use it with Karabiner without wasting another shortcut.
