I have two suggestions which would both be amazing and make a huge difference if they were made available.
First suggestion, I would really like to be able to hire someone to go in and edit my blank products without giving them access to everything. Right now it is not possible without also giving that person access to everything in the back end (finances, reports, etc...). Would like to be able to set limitations to a users account so they can edit products but not actually see things that should just be for management to see (sales, reports, etc...).
Second suggestion, would like to be able to my Magento website (and M2E pro extension) to be able to speak with Deconetwork. Doing so would allow the inventory to communicate across the sites.
