Some open tasks, good for getting started with the code base ;)

* Add scrolloff

* Currently auto-follow is active after 10 seconds of inactivity. It would be

nice to make it configurable, and allow to disable it.

* get rid of old-time dependency

* use -XNamedFieldPuns for ListWidget http://www.haskell.org/ghc/docs/7.4.2/html/users_guide/syntax-extns.html

* use `tagged` packages instead of undefined

http://hackage.haskell.org/package/tagged

* allow to move songs on the playlist around, maybe use J/K to move down/up

* Add option to skip (move!) over an album

* Add command insert-album (similar to add-album)

* Try to stay at currently selected song on ListWidget.update

* Sort library on (Artist, Album, Disc, Track)

* Update filter-view after update

* Detect errors on :source (see TODO in Command.hs)

* filterPreview is very slow if you append to the beginning of the search

term. Can we fix this by using a `Map` as cache?

* Use a zipper for ListWidget

* Add command :set autofollow=<timeout>, that automatically sets the

cursor position in the playlist widget to the current song, when the current

song changes (but only if the cursor has not been moved for <timeout>

seconds)

* The git version of MPD reveals the base path to the music library, so we can

use it as a default for set-library-path

* Allow to customize formatting for playlist/library/browser

* Make sure that :insert works on directories/playlists/playlist items

* Find out whether search is faster if we use Text or even the UTF-8 encoded

ByteString for matching.

* use strict-concurrency?

* update :help and :map output when mappings are added/removed,

currently they are only updated after after typing :help/:map again

* Write startup message with current date into log

* Detect when date has changed since last log message, and write a day

changed message in those cases

:help ideas:

* Show all macros in the default output as well? Currently only macros that

correspond to a single command with no arguments are shown.

* Parameterize :help, :help <macro/command> would pull up a TextWidget with

the documentation for that particular command.

* Remember the position of the cursor on the :help screen in between opening

and closing it multiple times.

* update help widget, when a new macro is defined

ISSUES:

* The actual value of a ctrl-key-combinations depends on the terminal, so

we may need to make some effort to get that right in a portable way

* We still have some startup flicker. My current guess is, that we only get

rid of it if we fetch all data to draw the initial screen before calling

initscr/start_color.

* Breaks in ugly ways when losing connection to MPD

* Browser needs to reload the current directory on EvLibraryChanged, this

should be done by recursively moving in from the TLD downwards as far as

possible.
