Very poor usability.
Tried google takout to download my pictures which they delivered in 13 download links (all zips). Could not find ONE of them with DTA. Instead I got a "download manager" with 31 downloads that have such useful names like "index" or "download" where the URLs are not visible. There is a short pop up when you click on the name with the URL truncated to a totally useless string ("https://takeout.google.com/takeout/...") you cant even copy .
I have no hope that this add-on will transform into something useful in the next year, so I de-installed it.
