This feature can be enabled by choosing a destination for the
`shared drafts category` site setting.
* Staff members can create shared drafts, choosing a destination
category for the topic when it is published.
* Shared Drafts can be viewed in their category, or above the
topic list for the destination category where it will end up.
* When the shared draft is ready, it can be published to the
appropriate category by clicking a button on the topic view.
* When published, Drafts change their timestamps to the current
time, and any edits to the original post are removed.
- clear line detection cache on category change
- don't show last visited unless latest / descending
- improve perf of last visited detection algorithm
FIX: endless spinner when /categories is set to homepage and you click the home logo
FIX: latest column should respect topic state for the current user (new, unread, etc.)
FIX: post count should have heat colors applied based on like ratios
FIX: Add "More" button at the bottom of the latest column
UX: The topic count number in the categories panel should be slightly larger
When a user is viewing a category they do not have permission to create
a topic in, they are still prompted to create a topic if they are at the
bottom of the topics. This fixes the issue, as well as disabling the
New Topic button if they don't have permission to create a topic for
that category.
We cap new and unread at 2/5th of SiteSetting.max_tracked_new_unread
This dynamic capping is applied under 2 conditions:
1. New capping is applied once every 15 minutes in the periodical job, this effectively ensures that usually even super active sites are capped at 200 new items
2. Unread capping is applied if a user hits max_tracked_new_unread,
meaning if new + unread == 500, we defer a job that runs within 15 minutes that will cap user at 200 unread
This logic ensures that at worst case a user gets "bad" numbers for 15 minutes and then the system goes ahead and fixes itself up
