By the way, a great idea. I think if TabTrader really can add even more exchanges to its application, it will be just wonderful. Because I use this program very often. Especially when I do not have a computer and some kind of project start to pump up. This happens very often.
Yes, they have a plan to add a lot of new exchanges. Take a look at the trello link.
When I started this thread there were about 5 new exchanges added to the voting poll but now I see more than 30 listed.
From what I can tell they start working on adding them when the votes for each one exceeds 50
So, don't forget to vote guys!
