#       /a-timer-to-set-up-different-alarms-simultaneosly

# DATE: May 31, 2018. Modified Nov 21, 2021.

# UPDT: 2018-06-07 Add new index for check box: "automatically close
#           progress bar display when all Sets finish". Remove '~/.multi-timer'
#           to delete configuration file before running update.

#       2018-06-19 Set fWindows flag to TRUE/FALSE instead of true/false.

#       2018-11-04 Early exit call Cleanup ()? For some reason sysmon-indicator
#           still displays: '~/.lock-screen-timer-remaining'???
#           Alarm only sounding for first timer but pop-up appears for all???
#           See changes to /etc/pulse/default.pa below:
#### Automatically suspend sinks/sources that become idle for too long
# Nov 4, 2018 - causes 3 to 5 second delay if last sound was 30 seconds ago.
# So you get sound delayed unpausing video or miss multi-timer alerts. Add #
# load-module module-suspend-on-idle
#           Although this fixes delay when switching between sound sources,
#           still change default alarm to sound file over 5 seconds long.

#       2018-12-05 HDD LED indicator flashing constantly while progress bars
#           are updated / program sleeps. Make LastWakeMicroSeconds dependant
#           on lost time log enabled only.

#       2019-03-23 Change default number of timers from 17 to 10 which suits
#           Windows 10 better and is more realistic number for most users.
#           Change grep arguments for "fWindows10" flag.
#           Put "Linux" or "Windows 10" as title prefix.
#           Set Windows 10 Sound file default to C:\Windows\media\Ring05.wav.
#           Error when notify-send command installed (minimal Windows 10).
#	    Override "/mnt/c/Windows..." to "C:\Windows..." when invoked.

#       2019-05-22 Suppress Transient Parent messages

#       2019-08-07 When quiting timer progress display spinning pizza remains
#           in application indicator driven by indicator system monnitor.

#       2020-09-10 Add Geometry option initally limited to parameter 1.

#       2021-01-31 Use /run/user/1000 to prevent hard disk activity light flash

#       2021-09-07 Change KEY="12345" to random number. Allows restarting.

#       2021-09-13 Use /run/user/$UID for multi-user systems.

#       2021-11-21 Remove dbus-send and use "loginctl lock-session" which is
#           a more universal way of locking screen in Linux.
