What you are describing for the master-sleve
layout can be achieved with either, XMonad.Layout.Grid or Tall layout (more likely, other ways to achieve this).
The stack layout on the other hand can be achieved through the XMonad.Layout.Accordion? And if you are not a fan of that you could always refer to the XMonad.Layout.Tabbed.
Extra:
- mirror functionality where you can rotate your layouts. Mirroring
XMonad.Layout.Tabbed
results in a stack-like layout. - magnifying glass for your layouts and much more!
- Not a fan of a specific layout and want to adjust it a bit? XMonad.Layout.LayoutModifier is your friend!
- XMonad.Actions.WindowBringer to bring window into focus on demand.
- XMonad.Layout.ToggleLayouts toggle desired layout on specified binding.
Only if simplex-chat had better UI…
