Checklist:

• [*] I made changes both for sync and async

[coder2020official]

No

why?

[coder2020official]

1. Bad implementation
2. No steps in async please

[hiddify-com]

It is based on your recommendation that suggest to use state

It is really useful to have steps in async

The step in sync is buggy also. It does not process middlewares.

[coder2020official]

Steps are an old, somewhat "deprecated"(though not yet and won't probably), so there's no point of improving them when there's a solution(states) which I am currently working on to even further improve

[hiddify-com]

the problem of state is that we can not have more complex workflow
for example when we want to get 10 elements from user it is so hard to be implemented by state

[coder2020official]

What do you even mean by "10 elements"?
10 inputs?
I am working on an easier solution, some class that will take care of this

[hiddify-com]

yes 10 inputs from the user

great thanks

@coder2020official Thanks for your great job. It would be great if we can have a timeline about your solution

[coder2020official]

Hi, my solution never came to existence, and I haven't had enough time recently either. I wouldn't mind re opening this.

I'm open to proposals, or I'll look at this issue again in December and see if there's any way I can simplify states logic.

Also, I have re implemented states to make them easier to use :)

[coder2020official]

I'll open an issue
