The latest update of Mesh Editor is now ready. With this release there is improved support for Unity 5.x and for the Mac. While I tried to continue support for Unity 4.x for as long as possible, it has now become unmanageable due to the major differences between the two versions.
All of the programs that use a hotkey now check for both the Ctrl and Command key by default as well as the custom hotkey.
