Updated TODO list.
Update package documentation.
Add another idea to the TODO list.
Add conversation and topic start times.
Add an initial function to format durations for various things.
Counter mostly works. Need to fix deleting active items and making new items active.
Massive changes, but we should be on the right path.
Timers should all work correctly now.
Last few tweaks to prevent the timer from disappearing and reappearing.
This should prevent bogus "forever-long" durations on past topics.
Fix typo in comparison logic.
Merge remote-tracking branch 'origin/dev' into dev
