Reintroduce some options removed with v7

[lwouis]

Hi everyone,

When we introduced v7, the big goal was to #351. I think we achieved that. Thanks to @Allsochen's hard work, we were able to move from a page that 1% of users understood how to use, to something that looks like it was designed by Apple themselves.

Before v7	After v7

We've added many new features as well. Added visual illustrations of advanced features, etc. It's a huge win overall for most users.

Along the way, we've had to remove some advanced customization. We removed it because it was too complex and a detriment for the vast majority of users. We also removed it in some cases because it was not a good idea to keep it and have to maintain it on our side, as well as to support users opening tickets with very exotic setups. Context for why manpower on our side is an important consideration: #1179

After v7 release, many people have sent feedback that they noticed a feature was gone, and they wanted it back. This was expected. We're now looking at how many people ask for certain features to be back, and are considering reintroducing a select few. This ticket tracks this, as well as being a notice we can redirect people to.

Current candidates we are considering:

• Mouse follow focus
• Adding an XS and XL Appearance Size
• Being able to adjust the switcher width
• Providing a Style with App Icons and Titles, with all Titles visible at once

Thank you 🙇
