Rated 5 out of 5 stars
It’s so perfect that I encouraged to try the beta version. I like it, it’s beautiful. But I think it would be nice if it was possible to open the manager window in a tab or at least there was an about-page for it.
EDIT: I love open source softwares! Searching the source I could find how to open DTA Manager in a tab: "chrome://dta/content/dta/manager.xul" :D
