Ability to search a Team and a Channel
Searching should be able to be narrowed and limited to the scope of what is currently selected. That would go for Chats, Teams level, Team level, channel level. It would also be nice to access the indexed content in OneNote and other Office files and text files.
If you have the same channel in multiple teams it's impossible to find the team/channel combination your locking for. When you filter your teams it should show ALL channels of the team you've filtered.
