That's not an efficient solution. You click an invoice, it takes it's time to open in the same window, it's not the one you were looking for, you close it, THEN you have to remember which invoice you just opened up so you can go to the next. Repeat the cycle and you'll spend your whole life looking for the one particular invoice. On desktop, I can sift through a clients invoice's and find a specific one within a few minutes, I spent an hour yesterday combing through a client's invoices and never found the one I was looking for.
