This introduces a more dynamic system of activity scoring, to improve
the way bubbles "bubble up" due to their activity. There are a few
different parts we can tune here, and it's likely we'll need to make
adjustments once we get a feel for how this works in practice.
The basic idea here is:
- We assign points for certain types of event that happen on a bubble. A
boost gets 1 point, a comment gets 10 points, and so on.
- These points decay over time, at a rate of 50% per day. So old
activity is worth much less than new activity. Bubbles should rise up
quickly when acted upon, bit will float back down if left idle.
- Some comments can score higher than others: the first comment from
each person on a bubble is worth more (20) because it signals that
more people are getting involved; and comments that follow a comment
by a different author are also worth more (15) because that signals
there's ongoing conversation between people, not just a series of
notes being left by one individual.
In terms of implementation, we persist the score on the bubble
whenever it changes, but we handle the decay on the client side. That
allows us to cache the bubble representation without having to
continually change it while its activity decays.
We also keep a separate `activity_score_order` attribute on the model.
This can be used to sort the bubbles in order of "most active", without
having to think about the decay.
Otherwise the text will get out of date. For example, a new notification
will say "Less than a minute ago", which is not true for very long if
the page isn't refreshed.

Leave some space for the tray
Let's not assume it's a due date
Avoid overlap
Let's try without the big drag button, extend beyond the column a touch
Tighten labels
Match notification dot
Spacing
Add more context
Avoid leaving the tray open
This shouldn't be here
Paginate the read notifications
Add a test case
Split up a big view
Allow filtering by stage
Send beacon request on disconnect as well
Wire up notifications "Mark all as read" button
Add unread dot
Set state for when there are no new notifications
Move to right side, smooth transition
Open tray on click, stub mark-as-read button
...
Since we're rendering according to the local timezone, we'll need to
include events that fall before or after the specific date on the
server, as they might get be inside the current day in the client's
timezone. So let's just grab a window of events either side of today,
and then hide anything that falls outside the client's day.
* main:
Don't round up in time distance expression
Tidy Gemfile
Banner for draft state
Drafts should always use the dashed outline wherever they're displayed
Unnecessary parens
Use distance to nearest edge
Simplify overlap logic
Fix divider drag jankiness
Use cache-friendly "time ago"
positionedClass -> installedClass
Pull out moveDividerTo
Before comes before After
DividerElement -> Divider
Clean up divider-controller
Drag bubble divider
This is so we can dismiss any notifications that arrived for a bubble
while we were viewing that bubble. Otherwise, they'll stick around until
we leave the page and come back.
