When creating a new transaction, you will notice that it comes over / on-top of whatever (non-transaction) page you were previously working on. So that once you finish creating it, you are returned to the previous page. For example if you were on the customer center and are creating an invoice for a particular customer, then on save (or cancel) of that invoice you will be taken right back to the customer center that is now refreshed with the transaction you just created. The frustration of saving a transaction and navigating away somewhere no longer exists.
There was lots of feedback around being forced to scroll all the way down the transaction too often to save. The buttons on the transaction page are now much more accessible than before even if you scroll the page. You no longer have to go hunting for them by scrolling to the bottom of the screen, they are always stuck to the bottom. All the save options are always in the same place at the bottom of the transaction as well as a More button that contains any additional actions you may need.
