Proposed event chains

[UberWaffe]

Here is what I plan to do for event chains.
The basic idea is to have something like what you find in games like FTL or Stellaris. A message window with one or more options to choose from.

An event chain consists of:
One or more steps.
One step marked as the starting step.
A unique identifier. (So we can start the event chain from actions.)

A step consists of:
Actions to take when the step is started / reached.
Custom message to display.
0 to 10 option buttons. (A step with 0 options automatically has a close button, and ends the event chain.)

An option button consists of:
A label.
Conditions that determine if the button is visible. (Can be seen.)
Conditions that determine if it is active. (Can be pressed.)
Hover-over text to display if the button is visible and enabled.
Hover-over text to display if the button is visible but disabled.
Next step in event chain. (Or none, which ends the event chain. Can point back to a previous step.)
