After you did a deployment from a sandbox to GIT (Github in my case) you have the option to create a Pull Request right from that screen. The default target branche is "main" even though my default branche in Github is set to develop.
It would be great if Gearset follows that default branche that is set in Git OR has a way of defining default target branche in Gearset.
The risk now is that someone might overlook this, make a pull request against main, someone else also overlooks this and merges it into main. With CI jobs on main this could become a huge issue.
