For ease of use, provide `fixSteamFlicker` as a pre-packaged
`floatConfReqHook` that can easily be added directly to a
`handleEventHook`.
Also, for discoverability, re-export it from X.U.Hacks.
Adds event hooks to communicate with trayer or, more generally, with
other tray programs. For convenience, a standard query for trayer is
also provided.
This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.
