I can never get this to work. I'm using a Macbook. :(

Terrible! Here is why. When I type the sentence in CAPS and use the extension, it converts it to a sentence case. It works, right? Here is the problem: when I remove the first letter and change it, the sentence reverts to CAPS. Logically, it would stay as it was even after the change, but it's not doing that. The extension is extremely buggy. Uninstalled.

I love this extension from the bottom of my heart, but it stopped working on Chrome yesterday. It's working fine on Edge, tho.

I love this tool, it seems to work fine for plaintext, but it doesn't seem to work in WYSIWYG editors.
