Back in the old days we used to customize views' templates from the tool
portal_view_customizations from the ZMI.
This tool has no UI (User Interface) and could beat you whenever you don't expect it.
This package uses the well-known
z3c.jbot under the hood and allows you to customize templates TTW (Through-The-Web) from the control panel.
Overrides are stored on the filesystem and you can version / backup them as you like!
