Hello,
Not sure if I installed wrong or if it is an error. Steps I did: download, unpack in c drive, chrome> extensions, become developer, load unpacked. add to toolbar, go to MIT app inventor, reload page. No change in options seen. Toolbar did not work.
Note: Error message showed when adding extension.
