Con Extension / Add-on limited to browser
Its function is limited to reading whatever text is selected or readable in your web browser.
Con Not multi-computer friendly
It is a PITA to deactivate a voice on one computer just so you can use a voice that you've purchased with your account on the same account but on a different computer in an attempt to not pay twice to use the same voice on two computers. Users have to make that choice, deal with the hassle of deactivating/activating voices or pay multiple times for the same voice for however many computers you use.
Con Have to fool around with permissions to install voice
For a supposed "manager app" it should deal with permissions by itself and not depend on users knowing how to fool around with that.
