Hi Carlos, thanks! V4 can be used side-by-side with V3 and in fact I'd recommend having them both especially at the moment while there are rough edges being worked out. But it is my goal to stabilize v4 rapidly and get it to full parity with v3.

For migration it's just any custom scripts that you will need to copy over from the v3 commands folder into the v4 commands folder. You can copy the contents of the entire folder over and just say no to overwriting. Shortcut key definitions will come over automatically since they're stored in moi.ini and v3 and v4 will use the same moi.ini file.
