Perplexity has became my go to. I got stuck not knowing how to change custon zap amounts so I asked it how. Got the answer.
"Specifically, search result mentions "Adds double-click to custom Zap amounts and messages" as a new feature in version 0.30.2 of the app. This indicates that you can double-click on the zap button or icon to set a custom zap amount, rather than being limited to the default 500, 1000, and 5000 sats options.
Additionally, search result from the Reddit thread confirms that you can change the default zap amount in Amethyst by long-pressing or double-tapping on the lightning/zap icon. One of the comments suggests holding down the zap button to set a custom amount.
So in summary, while the default zap amounts are pre-set, Amethyst does provide the ability to customize or set your own zap value by either double-clicking/tapping or long-pressing the zap button or icon within the app's interface."
