We will be adding an edit in Dreamweaver feature in a free update soon because of the popular demand. Most issues that have come up so far have been associated with:
1) Doesn't work properly with Magic_Quotes_GPC enabled... we'll have this fixed in the update
2) Confusion when both a testing server and remote server are defined. It will try to use your testing server when it exists, but you may need to manually upload the connection file.
3) Using on a powercms created site where powercms is installed to a sub-directory. It can't find the connection in the sub-directory, so you need to manually create a copy of the powercmsConnection file in the root /Connections folder.
We will be working on correcting these issues as soon as possible, but we should have work arounds if you are running into any of these in the meantime.
