Slack Multi-Teams Overview

#
# Slack Mutli-Teams Overview.
#
# by Harry Löwen
#
# Provides an overview of unread channels, unread messages and channel histories.
# Features: multiple teams (workspaces) handling,
# 'mark as read' and 'open in slack' buttons,
# display all channels or only unread ones.
#
# Uses Slack Legacy Token (from now)
# https://api.slack.com/custom-integrations/legacy-tokens
#
# Refresh rate is set to every minute.
# Because: 180+ lines of code and 4+ requests running per team (one channel, one user)
# For a simple unread indicator check out: https://github.com/matryer/bitbar-plugins/blob/master/Messenger/slack-unread.1s.py
#
# Feel free to customize settings, colors, all-done-messages, etc.
