@item
The layout is based on splitting frames into subframes which can be split
again or can be filled with windows (similar to i3 or musca).

@item
Tags (or workspaces or virtual desktops or …) can be added/removed at runtime.
Each tag contains an own layout.

@item
Exactly one tag is viewed on each monitor.  The tags are monitor independent
(similar to Xmonad).

@item
It is configured at runtime via IPC calls from @command{herbstclient}.  So the
configuration file is just a script which is run on startup (similar to wmii
or musca).
