Mark Estimates converted to invoices as "accepted" or similar
I guess the title describes the suggestion, but currently in Estimates, each estimate can display "expired", "viewed" etc - but it is quite odd that the estimates that have been converted to invoices don't reflect the conversion.
This would be really handy when for example a customer hasn't yet received the Invoice, but they give you a quote number to look for or just so that you can see what sort of percentage of conversions are made etc.
I'm sure there are many other reasons this would be handy, but it would be a good addition. - thanks for the great system.
