A few things that would help my business on etsy..
1. The ability to have a signature on my messages. I type
Shabbyscrap over 50 times a day
2. The ability to filter the messages to be able to read new messages only. When you get a lot of messages they can get lost. Again when the shop is busy I get 50 new messages a day and replies on top of that. When I answer my replies go to the top of the page and things gets buried quickly.
