View source for Channel Sidebar (UI)

The channel sidebar currently has two different states, "conversations" and "viewing server".
== Conversations Sidebar ==

The conversations sidebar shows a short navigation menu to:
* [[Home (UI)|Home]]
* [[Friends (UI)|Friends]] (hidden on mobile; shown in [[Bottom Navigation (UI)|Bottom Navigation]])
* [[Saved Notes (UI)|Saved Notes]]
With a list of direct messages below (descending order by last message ID with a fallback to channel ID).









== Server Sidebar ==

The server sidebar is composed of the server banner with the title on top, and a list of categories and channels below.

Categories may be collapsed, and continue to show the active channels when collapsed.

=== Ordered Channels Algorithm ===

# Initialise a set U of uncategorised channel IDs from server channels the client may access.
# Initialise an empty list of categories C
# If server.categories are defined, for each category:
## Remove all the channels defined in the category from set U
## Add category to list C
# If the set U is not empty:
## Find the "default" category if it exists in C
## Merge the "default" category channels if they exist with and preceding the set U
## Create a category with id="default" and add it to the start of the list C if it does not exist
# Return the list C
