I think TS might be a bit too feature filled. I am sure the developers have a good reason for every single feature they added, but it is easy to get carried away with features as you think of more and more use cases that you want to have covered. But as you put in more features, new users will feel increasingly overwhelmed when they first arrive on the website - and possibly be scared away. I felt like it took me too long until I understood everything, and am still not sure about some things (Why are cards sometimes yellow??)
I think alot of information does not need to be shown or could at least be a hidden away, maybe in a mouse hover window. Same with some of the function, maybe they could be grouped up in a single button/icon that opens a dropdown menu when clicked on. And finally some of the features could be reconsidered. Are they really neccessary. This might make TS a less powerful tool, but could potentionally help grow it's userbase.
