Prefer to have widgets force a draw when their data changes. This should
reduce draws (unless the user has a module installed that updates >=
1/sec, the old draw default).
This should also remove a source of some of the race conditions that
users were experiencing (though not all, there are still many).
Widget titles can now be specified in the config file via a 'title' key.
Example:
wtf:
mods:
todo:
title: Tada
which can include emoji. No need to force everyone to look at my emoji,
now they can define their own.
This module displaysw which source is providing power (AC or battery)
and for the battery displays the current charge capacity, how long it
will last, and the battery state.
