I have done a few of tests with Cin20201020 release by git.

I'm not sure this automatism is a good idea.

I understand what Pierre meant.

I think that an User might just want to save space.
Sometimes I use Gang modes only for save space on the timeline, in my case I use it for Video tracks.
And it may occur that I have to disable "Play track" on one or more Slave tracks (an example may be Mixer Viewer, Multi Camera editing). So I have the "Play track" of the Master Track enabled and all the "Play track" of the Slave tracks disabled: with the new changes, it doesn't work anymore.
Like Andrea_paz wrote, is it possible to make this feature an option in Preferences (or where you think better)?
Thanks!
