Increase/ Decrease Burner Power by % relative to current value

[feichong83]

As of now, user can increase/ decrease burner power by an absolute value, ranging from 0 to 100 by clicking an burner event button configured by the user. Let say, if current burner power is 40, if user click on the button -10, burner power will decrease to 30.
However, burner power is often decreased by a percentage as thought in a roaster's mind. Let say, during development ratio at 12%, a user will target a decrease of burner value of 50% from current value.

New idea:
Can we decrease and increase the burner value by percentage relative to current value.
Example:

• User configures burner event button as "-10%", "-25%" and "-50%".
• Let say current burner value is 40:
  1. If user clicks the button "-50%", the burner power goes down to 20.
  2. If user clicks the button "-25%", the burner power goes down to 30
  3. If user clicks the button "-10%"., the burner power goes down to 36

To the New Year
(based on Rilke, paraphrased)

And now, we want to embrace a long year that lies before us, new, untouched, full of things never yet seen, full of work never yet done, full of tasks, demands, and challenges.
We want to learn to take it as it comes, without letting too much fall away from what it has to offer
to those who require it, what is essential, weighty, and great.

…a happy New Year’s morning

Using external scripts: Write a Python script that is called via "Call Program" to read the current value and calculate a new percentage value using the preset absolute value button. If you want dynamic percentage adjustment functionality, use an external script to implement the calculation logic.
