I like what mycelium does. You type the amount, and there&#x27;s a button that will change state on every press, and cycles though &quot;generous&quot;, &quot;normal&quot;, &quot;economical&quot; and &quot;stingy&quot; or something like that.<p>That way, a user doesn&#x27;t have to know what value to use. You can also set this once in settings and never see it again, except as a report.
