Title: Add Link "unit settings" to "paid all" confirmation page
Summary: When you click "pay all", it takes you to a screen where it tells you what you just paid, and there is a link to "continue paying". This also needs a link for "unit settings", as it is almost always the next link that is clicked on.
Details: Nine times out of ten, the reason a person manually goes to "pay all" is because they want to change unit settings (unless they are trying to save a gold piece by manipulating the rounding or are short on gold.) This seems like a logical link to have here. This could also feature on the screen after you have paid only your unit.
Benefits: This would save time every time you want to pay and change unit settings, with a minimal amount of coding (as far as I can see).
Possible Downsides or Exploits: None.
