This is a compilation of UserStyle CSS scripts for Stylus/Stylish that make websites I use less annoying. Some sites are too distracting or inconvenient to use as provided, and some features are of no interest to me and just take up space and detract from the content. The scripts are utilitarian and are not intended as visual themes or ad-blocking scripts. These are primarily of personal interest in making the internet more pleasant for me to use, but feel free to ask questions or provide additional CSS customizations or feedback and I will consider making changes.
Read the tops of individual files for descriptions of what they do.
1. Get the Stylus browser extension
* Some of these scripts use the CSS :has() selector. If you are using Firefox v120 or earlier, you may need to enable the layout.css.has-selector.enabled flag in about:config.
Take a look at the UserStyle previews below and click any of the 
Alternatively, you may browse to any UserScript file on GitHub and click the Raw button in the top right corner of the viewer. The Stylus extension should recognize the script and offer to install it.
The Stylus extension will show a gear icon for every installed style that has user customizations available. And you can always choose to disable the entire UserStyle if you need to remind yourself of the sad life you once lived.

Adds Keyboard shortcut reminders to Gmail, helping you to navigate without the mouse and work more efficiently. These keyboard shortcuts have always existed in Gmail, but adding reminders to the interface makes it easier to learn and use them.
Many of these keyboard shortcuts are considered 'advanced' and must first be enabled through Gmail Settings. To view and enable all shortcuts in Gmail, type a '?' into nothing (with no textbox selected), or follow these directions.
This UserScript assumes that you are using Gmail's default keyboard shortcuts. If you have opted for custom keyboard shortcuts, you'll have to edit this CSS file yourself to match the shortcuts you have chosen (don't worry, it's not difficult). This is also styled to work best with Gmail's default visual theme, and has not been tested alongside other themes.
I chose not to add shortcut reminders to the Compose email window, because this is one place in Gmail where you can hover over most buttons to see a tooltip with its keyboard shortcut.
Hides unnecessary commands when composing an email, such as buttons for undo, redo, bold, italic, underline, emojis, attachments, inserts, etc. The features are either unnecessary or are more easily accessed through shortcuts or by drag-and-drop. It also places the entire text formatting command bar in line with the Send button, rather than leaving it floating overtop of the bottom of the email. The Remove Formatting command is now a single click away rather than three!
Adds Keyboard shortcut reminders for:
- Start chat
- Select previous/next chat
- Focus on chat list
- Focus on message text box
- Focus on current chat body
- Add emoji, sticker, gif, attachments
- View Settings menu
- View conversation details
- Delete or Archive conversation
Supports both Light Mode and Dark Mode.
Note: Some of the shortcuts have changed since these screenshots were taken. The script is up to date, but these screenshots are not.
Worksheet view:
- Adds a straightedge - horizontal and vertical dashed lines to help identify the row and column of the active cell.
- Adds a smooth movement to the active cell border and dashed lines when moving between cells.
Improvements to the Google Sheets tab bar:
- Adds a Scroll Left button to the left side of the tab bar.
- Reduces unnecessary horizontal padding along bottom bar.
- Hides "Explore" button text.
These UserStyle scripts have not been tested on anything besides Chrome with the Stylus extension, and the particular websites as they exist today. Some of the scripts have been made user-configurable through Stylus using @var declarations in the ==UserStyle== header, and the LESS CSS preprocessor is used for the CSS Guards feature to permit disabling of optional CSS selectors. Aside from that, the files are pure CSS and can be used on other platforms.
Note: I previously made custom AdBlock filters for a similar purpose, except that they run on the uBlock Origin extension. Stylus has proven valuable enough that it is now a full-time extension of mine, so I no longer need to use/abuse uBlock Origin in that way.
