Recently had to start using MS Teams at work. What a terrible UX: truncated message widths, even for code. No syntax highlighting, markdown-ish syntax only works when you type it in their little editor—when you paste it in it doesn't format, isn't smart enough to auto-start a new message when I start typing, hides bottom of message—even when there's only one line left, etc. Just a bunch of little stupid things that a…
The markdown formatting doesn't even work consistently. Some days things show up bold, some days they don't, some days I get inline code, some days I don't. It's very random and seems to be based on my typing speed at the time. That is, type ` and then wait a moment before typing the next bit and it works more reliably, but if I type like normal (around 100 wpm) it rarely registers properly.
Starting a new chat with someone in your organisation that you haven't chatted to is also annoyingly slow. This one I keep forgetting. So I search their name in the search bar, choose the hit from the dropdown and immediately start typing, only to notice that my initials 10 keystrokes didn't register, because the new chat was still initialising.
I'm curious, do you touch type? I'm also at about 100wpm, but only thanks to learning to touch type.
