The extension is great but not perfect when it works. However, the extension will pretty regularly break in the background and simply not work until it decides it wants to again. There is no obvious fix or troubleshooting for this issue.

Additionally, even when it works some of the integrations and other features are rather obstructive without room for customization. For example, the google suite integration just loves to put the DeepL button directly over critical functions on gmail and google docs, getting in the way of my work. Ultimately, i've turned all of these integrations off despite their theoretical convenience.
