4 things that were really great, but are now frustrating: 1) It's great that you can press 'd' to bring up the folder menu when you want to move an e-mail, but not having the ability to press 1-9 to send it directly to a folder means extra mouse movements or several additional clicks. Being able to press 2 buttons quickly was so much better for repetitive stress; 2) having a colored background in light mode was great. I'd prefer dark mode, but sometimes when you copy something (like from ChatGPT) and are in dark mode, you have to make the text white, but then nobody else sees it when you send it. So I have to stay on light mode; 3) you used to be able to copy the text of a BCC group. Now it's impossible; and 4) when entering an emoji, you used to have the emojis that you use the most (or maybe they were the ones you used most recently). Now, to get to the thumb's up, which I use often, you have to type thumb and then click.

So it seems like this kind of programming/features are so simple from a programming standpoint, so I'm not sure why they were removed because they were great features.
