Ok, that was not so hard... I found it, at least how to backup the plugins...
For those who are looking for how to sync the plugins:
> Go to the 'Advanced tab' > Click on "Copy plugins to clipboard" > Paste it on a text file and save it > On your other computer, just copy that saved text and > Click on "Add pluginData from clipboard".
that was quick, thank you!
(It's the current solution!)
