I have released another RDPManager package. This one has minor bug fixes, and the ability to edit the connection statistics for any machine. The new Most Used feature (at the top of the Recent menu) relies on connection statistics to determine what machines show up there. Using the new dialog, you can promote a machine to this list or demote a machine if you have one you don't like in there. You can find this new edit function under About, Connection Statistics, and the select a machine and then you can click Edit or Clear. Edit will let you change things, while Clear resets the selected machine to 0.
