We want improvements to search:

CTRL+F SHORTCUT
I wanto to find messages inside a chat or channel with CTRL+F.
It’ll allow me to quick search messages in a specific conversation.

PARITY TO SKYPE SEARCH
Like in Skype chat, we need to be able to search text strings from conversations

IMPROVE SEARCH RESULTS VIEW
I feel as though the conversation view looks a bit cluttered as is, and conversation threads are not as readily identifiable as I had hoped they would be. Some suggestions are: Add the ability to include a Topic Header for a conversation so that you can easily ID a conversation you are interested in, perhaps alternate the colour theme between conversation threads (i.e. first conversation has a purple background, the next one has a red background, then green, etc.) to very quickly distinguish between threads.

SEARCH WIKI and OneNOTE
Make the search bar also search through content in Wiki and OneNote.

PARTIAL WORD SEARCH
Currently when you perform a search you will only find the exact word you type, but I think it should do at least partial word search, e.g., find the word “categorize” in the word “categorized”.

Aside from search functions for “Channel”, could we have a better search function for “Chats” too?

The problem is detailed above (the first two comments in the comments section) – usually,
Teams directs us to the words only (for Chats) but what we really needed was the full context, the surrounding conversation on that day. See attachment, where I was looking to be directed to 25 Jan conversation but search only turns up a specific section. How this would have worked better is if users could have clicked on that conversation to jump straight to conversations on 25 Jan.
Also – the search function cannot be filtered by Channels. For example, if you were searching “WIP“, everything regarding “WIP“ on Chats and across channels turns up, even though you’re only looking for it on a specific channel. Filtering does not help as it requires you to type a subject and then it doesn’t turn up what you require. Some improvements in this area would be really great!

The far left navigation panel seems to have a whole lot of blank space just calling out to be filled with things, and there is plenty of functionality within Teams that could be put there so users could reach it faster. That big gap between Files and Feedback is wasted space!

You should let individual users decide what goes in this space by giving them the ability to pin additional things they want there. I use the 'Saved' functionality a lot for example. It would be nice to have it out there only one click away. Perhaps I think a certain person, bot, or channel is important enough to deserve placement out there. Or how about a certain Tab somewhere.

Give the user the choice and allow them to make Teams their own!

When working in Shifts on in the desktop client, new requests are not very obvious. Only some requests can be seen as a pulsating entry in the Monthly view for example, but that requires you to have the month in question in view. You need to open the Requests view in Shifts to see the requests.

The obvious place for these notifications would be to have them visible in the Activity view in the client, where all other notifications are shown.

What would also be nice-to-have is to have a specific notification easily visible in Shifts itself, so that as a manager I can see that someone has requested something, and I can view and act on it.

Slightly surprising, the mobile client has better notification in this regard, where Shifts notifications are actually shown in the "Activity" view of the app.
