There are a few features I use all the time and most of the items on this top bar I never use.
I NEVER use: Get Rate, Assign To, Bulk Update or Allocate.
However, I am always using Mark As Shipped and Export Orders Also due to a problem with my particular shopping cart software, I need to navigate to Settings, Automation, Automation rules... scroll WAY down to the bottom (I have a lot of rules!), Re-process Automation, then CONFIRM. Boy that's a lot of steps!
Like customizing columns, I would love to be able to customize which action buttons are at the top there.
