Roadmap to 1.4

Update docs
nothing handled in xfpm_power_dbus_get_power_save_status; setting powersaving via dbus does not work?
fix incorrect display brightness “normal” level after resuming from suspend; or to describe it differently, reducing the level works, but it won't get set back to 100% but to some other level
remove options that are not working; we can add them back later
- System tab: “Prefer saving power over performance” - how is it supposed to work anyway (only when on battery)?
- System tab: Remove “Hard disks” section completely
  - the dbus call seems to have been removed anyway in udisks2
resize panel widgets on gtk style changes
help button does not work
~~automatically select first device in list on devices tab (usually details for AC adapter appear on the right, but the AC adapter entry on the left is not selected, which is slightly confusing~~

Optionally display a label next to the icon indicating remaining time and/or percentage
Fix plugin icon being cropped with themes that set xthickness/ythickness (e.g. weather-plugin handles this nicely)
Merge brightness plugin into battery plugin
- Something like: http://dot.kde.org/sites/dot.kde.org/files/battery_0.jpg ?
- Would look something like this in Gtk:
~~Hook up the device-entries to the respective page in the settings manager~~
When xfpm isn't running and you open preferences it asks if you want to start xfpm then settings quits, it would be nice if settings either continued to load or waited a couple seconds and relaunched itself.

Add checkbox to enable handling of brightness management ( = override kernel)
- no backlight control on T440s
- we can check and set /sys/module/video/parameters/brightness_switch_enabled
- we can check and set /sys/module/video/parameters/use_native_backlight
- because sometimes xfce4-power-manager might handle backlight better than the kernel driver (finer steps etc.)
~~hide/show tab when on desktop/laptop~~
~~Move brightness-settings from display tab~~
~~Add option to deactivate brightness notifications~~

1.6 (or later)

better handle machines that have more than one battery (especially warnings and remaining time, tooltip info about battery)
- UPower 1.0 has a concept of a display device that is supposed to fix that issue, but we do need it to work for earlier versions.
Use udisks2 for hdd spindown
let the user control spin-down time
add support for laptop_mode (might be linux-only feature)?
Consider doing a fade-to-black, if X11's screensaver extension is used (instead of gnome-screensaver or xscreensaver)
Detect installed/running lockers and add “Preferred lockscreen:” combobox to the settings-dialog (deprecates the “stupid” xflock script)
- Add “xfce4-power-manager –lock-session” commandline-switch (and also add that to xflock4 as first command to try)
- Related bugreports: https://bugzilla.xfce.org/show_bug.cgi?id=5359, https://bugzilla.xfce.org/show_bug.cgi?id=10217 (and many more)
- We should probably also add a timed-locking feature to xfpm, so it really controls all locking options
Add code to handle cpu frequency / governor settings, e.g. powersave/performance switch for intel_pstate.
Show current watt usage (upower energy rate available in battery info)
