I’ve found myself using the system track a lot since v2 was introduced. It’s the easiest way to copy material and also insert / delete bars. A lovely little addition to Dorico and very useful.
By way of saving a little bit more time, I would like to suggest some ability within general settings (Note Input Options?) to specify what I would like copied. I find myself regularly deleting time signatures, bar markings and rehearsal marks after copying a section. I don’t think I’ve ever kept any of those so if the option existed to specify what I wanted to be copied on a general basis I wouldn’t include those.
One other point, just on consistency. If I Shift-B in a bar and add one (+1), a new bar appears before the bar I’ve clicked in. If I click on the System Track for the same bar and add one (the plus sign), it appears after the bar I’ve clicked in. It’s not a huge point, I’m used to it now, but it might be good to make things consistent.
