AltSnap vs herbstluftwm

AltSnap has no write-up on Specifiction yet; its figures are above.

herbstluftwm is a manual tiling window manager for the X window system. Each virtual desktop, called a tag, has a tiling layer and a floating layer, allowing windows to occupy split frames or be placed freely. Frames can be divided into further subframes or filled with windows, and keyboard controls move, resize, and focus tiled and floating windows. Configuration runs through herbstclient and can be changed while the manager is running without a restart. Screen space can be divided into virtual monitors that need not match physical displays; monitors share a common pool of tags.
