Especially in case of shared string that are duplicated in browser and toolkit, it would help me a lot seeing in Machinery my own suggestions I have made, but not reviewed. To illustrate the use case better, my flow is:

1. Open files with missing strings in tabs.
2. Go tab by tab, add suggestions to all missing strings and close the tab.
3. Later review and approve the suggestions to ensure they are consistent and in a single commit.

Where the same string is in multiple files, e.g. "Pause notifications until %S restarts", and its translation is not straightforward, I need to use a search in the project to find the suggestion to copy it from the first string occurrence to the other. Instead I would like to see this suggestion in Machinery.
