Automatically follows your browser's language; can be overridden in Settings. Changelog • 2.6.0 - Fancy Fonts, our extension for bold, italic and other text styles, gets a line in the popup and Settings and one item in the right-click menu while it is not installed; the menu item goes after one click. After 20 conversions over at least three days, a "Rate Convert Case" link takes turns with it in the same places, and goes after one click • 2.5.0 - New kebab-case conversion, which keeps words in any alphabet, as the site's does. Conversions now match convertcase.net: Title Case, Sentence case and Capitalized Case handle abbreviations, initials, quotes and hyphenated words as the site does, and words that are also names (rest, polish, zoom) keep their own casing unless typed as the name; the developer conversions work in any alphabet and convert each line on its own. param-case is now Slugify and CONSTANT_CASE is SCREAMING_SNAKE_CASE, as on the site, and path/case is removed. Converting text that spans links or bold keeps them, and in a text box, an editor or Google Docs, Ctrl+Z undoes the conversion (text on the page that cannot be edited cannot be undone). The popup and settings follow the site's design, with dark mode. Copy After Conversion is also a switch in Settings, and the two stay in step. Fixed the menu changing for a background tab, counts resetting to 0, Google Docs overwriting the clipboard when converting from the right-click menu in Chrome, and large custom word lists not saving • 2.4.3 - Fixed the space after a word being deleted when converting - double-clicking a word on Windows selects the space that follows it, and conversions such as No Case, PascalCase and CONSTANT_CASE were swallowing it, so "Lorem ipsum dolor" became "Lorem ipsumdolor" All versions: https://convertcase.net/browser-extension/
