Thank you for your suggestions!
Couldn't get "Buy with MetaMask" button to work with other plugins
Can you explain about which plugins do you want it to be integrated with please?
No Timer???
There are already Timer plugins exists:

Will need to do a lot of customization
Can you suggest a way to do it simplier to customize please?
