syncthing looks interesting and I hope to use it for file sync on my small work lan. There are a couple of issues that are real show stoppers, out of the box.
 After install on a windows 7 pro box, and a virtualbox hosted vm on the same machine, the UI for syncthing opens in IE, the default browser for each instance. However neither machine will present the syncthing ui in firefox using the same url http://127.0.0.1:8384/. They just spin forever.
 Syncthing does not create an installation folder and program group etc. It seems that the installer is simply an executable. It almost can’t be running as a service…I think I saw a note about this somewhere and will track it down. But it is confusing for a new user that none of this is mentioned in the installation guide. (edit: I found syncthing windows installer and will experiment with it)
 The device key can’t be copied. I select it with the mouse and it gets deselected immediately. Surely one is not expected to type in the device id’s?
Essentially, for a user following the installation guide, it goes off the tracks right away. This must be a common experience for new users but I didn’t see entries like this in the forum, before posting.
