* 3.3 Filter Editor:
~~~~~~~~~~~~~~~~~~~~

The Filter Editor can be opened either from the button on the main
window, from the Filters... entry in the main menu, or by a Ctrl+Adjust
click on the iconbar icon (the latter being configurable).

The filter editor has information about the 20 filters that can be
defined. By default, all but one of these will be greyed out.

For each filter, the following icons are provided (from left to right);

Avail
Active
Name
Default
CopyTo
Reset

Avail
  This must be ticked before you can do anything else with the filter.
  It will not allow you to make a filter unavailable if it the only
  Active filter.
  Filters that are available appear in the filters menu.

Active
  This indicates which filters currently apply to the database. The
  active filters determine which tracks are present in the post-
  filtered list.

Name
  This is simply a descriptive name for the filter. Internally, filters
  are stored by their number, which is reflected in their position on
  the filter editor window. Filter names do not have to be unique,
  although this is recommended to avoid confusion.

Default
  These indicate what filter settings for each filter newly added
  tracks will receive. Typically, you might have one filter set that
  contains all tracks, and other filter sets that only contain small
  subsets. In that case, you would want to tick the defaults for that
  filter only, and leave the others unticked.

CopyTo
  This is greyed out unless you have more than one available filter.

  On clicking the CopyTo button for one filter, a menu will open
  listing all the other available filters. Clicking on the filter you
  want to copy to will copy all track specific filter settings to that
  filter. Any existing settings in the filter you choose as the
  destination for the copy will be lost.

Reset
  This will reset all the track specific settings for that filter to
  whatever the default values for that filter are.

The filter editor (and menu) will behave differently depending on the
option 'prefer single filters'.

If enabled, this option makes filtering behave more like it did in
AMPlay 1.5x. Specifically, with it enabled, clicking Select on a
filter in the filter menu, or on the Active tick box, will activate
that filter, and deactivate all the others. Adjust would allow you to
activate a filter, without affecting the status of the others.

If 'prefer single filters' is disabled (the default setting), then this
behaviour is reversed.
