Some URL extractors (like uripecker, which I'm too lazy to fix now)
don'r "see" URLs without TLD.  It's probably nicer to use fuller name
anyway (and use aliases only for SSH, where applicable).

... there's just too much space.

The 'history' mode allows incrementally creating item list by typing
items directly to dmenu.

Also, stderr and stdout are now kept automatically for all menus.

But secretly the reason is to show off bmo-nag

The rest is redundant.  On a healthy system, / does not need to be
watched so closely and libvirt/images uses sparse files so the info is
not so accurate.

The API is a bit misleading (and PlayPause is not implemented)

Used lxappearance(1) to choose the settings

Note that the bar is disabled by default; you will need to enable it
on-demand somwhow.  One possible way is wrapping clementine in a script
like this:

    i3-msg bar mode dock clementine
    /usr/bin/clementine
    i3-msg bar mode invisible clementine

However, due to i3 limitation, this will not guarrantee that the main
bar will always end up in the very bottom of the screen.  To work around
this:

    i3-msg bar mode dock clementine
    sleep 1
    i3-msg bar mode invisible main
    sleep 1
    i3-msg bar mode dock main
    /usr/bin/clementine
    i3-msg bar mode invisible clementine

Or vote for i3 feature request to make this more predictable:

The --pause option does not work in all versions:

GUI tool seem to remove whitespace so let them have their way
