How to implement this custom workflow, is it possible?

Hey!

I have read through the docs but couldn't find how to do exactly what I want. This is what I would like to have:

1. Disable "add to history button". Hitting enter on a calculation should copy it's result to clipboard and close rofi.
2. Hitting enter on a history element should do the same as hitting enter on a calculation
3. Elements should automatically be added to the history
4. Ideally, I could implement something like shift + return to copy the formula rather than the result to the clipboard but this is less vital.
