How do enable donation-only add-on features?

  1. Make a donation by PayPal
  2. Run Synapse and send the first five letters of the KeyCode of your device displayed on the first screen to the developer email.
  3. Wait for the developer's reply.
  4. After receiving the reply, run the Synapse.
  5. The add-on features will be activated and the current version of the add-on will displayed on the first screen of the Synapse.
  6. Enjoy!

I will use your valuable contribution to create a better kernel. Donations are an indirect way of participating in development and can be donated several times if you wish.
