Yeah, that has changed with the new track layout. You can’t drag tracks onto each other or move them sideways to create a group at the moment. You can still drag tracks in and out of a group, which should also work with multiple tracks, once it’s possible to select them.
Regarding the bus-order, I’ve asked about this before (quotes from another tread):

As it says…
Error: The bus send is disabled as it could cause feedback elsewhere in the signal chain.
Bus send instances must be placed in the same order on all tracks.
I must confess I do not understand why this is so.
Since bus sends “just” send to another track inside the hierarchy, where would the output of the bus feed the signal back?

This would be doable, if I chose to ignore delay compensation rules in cases where the routing bites its own tail.
Consider that you can insert plugins with latency between two sends on a track, and that you can have a bus return feed into effects with latency before being routed through another bus send. Thinking about it too long can give you a headache :-k
I haven’t thought about it anymore after this warning – no need for headaches! 😡
