Nice tool, which came just in time.

Took me a while to figure out how to sweep (hold ctrl while selecting one of the tracks on the right, then hit start), which could be explained in a slightly longer tooltip for start. The auto sweep creates a more jagged curve for me than sweeping manually, so I will have to play with the parameters.

thanks, good point. I will think about better information about that. Regarding the sweeping - reporting bug on github would be helpful, especially with logs and screenshot (S) with debug information enabled (F11). Some devices may have big latency I guess.
