Implements the suggestion from https://github.com/htop-dev/htop/issues/399#issuecomment-747861013
Thanks to the refactors from 0bd5c8fb5da and 6393baa74e5, this was really easy
and clean to do.
It maintains the "Tree view always by PID" option in the Settings, which
results in some specific behaviors such as "clicking on the column header to
exit tree view" and "picking a new sort order to exit tree view", for the sake
of the muscle memory of long time htop users. :)
htop is a cross-platform interactive process viewer.
htop allows scrolling the list of processes vertically and horizontally to see their full command lines and related information like memory and CPU consumption.
The information displayed is configurable through a graphical setup and can be sorted and filtered interactively.
Tasks related to processes (e.g. killing and renicing) can be done without entering their PIDs.
Running htop requires ncurses libraries (typically named libncursesw*).

Build instructions
This program is distributed as a standard GNU autotools-based package.
Compiling htop requires the header files for ncurses (libncursesw*-dev). Install these and other required packages for C development from your package manager.
Alternatively, for compiling sources downloaded from the Git repository (git clone or downloads from Github releases),
install the header files for ncurses (libncursesw*-dev) and other required development packages from your distribution's package manager. Then run:
./autogen.sh && ./configure && make
By default make install will install into /usr/local, for changing the path use ./configure --prefix=/some/path.
See the manual page (man htop) or the on-line help ('F1' or 'h' inside htop) for a list of supported key commands.
Support
If you have trouble running htop please consult your Operating System / Linux distribution documentation for getting support and filing bugs.
