Keyboard shortcut idea resize windows to a designated bounding area

so you would create a rectangle inside a screen and when pressing this key it would act similar to maximize window, except instead resize current or all to this custom area.

this would work well with tint2 which I set to sit above my panel but sits behind windows.
but might be too niche unless you guys see other use for it.

curious however I added a stack windows with offset feature.
which I think could deserve a key on it’s own.
