When presented with these buttons:

It is not apparent which button does what, and it is unreasonable for users to /fstack the buttons to see what they do 😝

If there could be tooltips for these buttons to indicate the left one is repair with your own money and the right is repair with your guild's money, that'd be grand 👍

As it turns out, the information is there, but only if you have items needing repair:

That will hopefully make implementation of tooltip for disabled buttons easier 😄
