Superb! No need for currency conversion. Rated 5 out of 5 stars
Hello, I read your plans for future features. Your add-on is a very useful tool for daily work at the computer. And I think that currency conversion is not necessary, because there exists an add-on that does this very well. People who also want currency conversion can install this in addition:
Your add-on is the perfect solution for people who only want unit conversion. And I think it should do only this and nothing else. Keep your add-on lightweight! I recommend to drop programming on the complicated currency thing and concentrate on maintenance of the unit conversion and its options.
Also, I'm always a little bit touched when I read how much time and love people invest into things like this and then share it for free with others. Sharing is what brings progress and prosperity for all. In case you ever decide to drop it due to lack of time or whatever, please ask the community if there's someone who will take the project and maintain it. I'm sure there will always be people who can do the job. Thank you for all your work. If everyone would share his productivity as you do, this world would be a very delightful place for everyone on this planet.
