I know Tau is only in development but I just wanted to make a suggestion just in case it isn't already planned. I would like to see sliders in Tau, The way I imagine them working is there would be a line that you would click at the start of and then hold and follow the line, once you hit the end of the slider/line you would release. Just like a normal slider really but in tau, I'm sure you guys know what you're doing so you would know how to do this and make it look good.
