You can have a single connection layout (but still have two window panes)

Do the following.

Click View > Single Connection layout

You can drag and drop from Local (anywhere in your PC) to remote but the opposite is not possible like Bigstar says.

However drag and drop works both ways just fine within the two windows of Flashfxp, which is very useful in comparison, when you get use to it and the local window you can pretty much use like a "finder", its only missing a search option atm.

You will find not many windows FTP programs behave/look like in a MAC, at all.
