Something that at any point can interrupt the workflow and run and either return or end it. This is for basically stuff like "change my language" (where the auto translator is bad to the level I wonder it passed any quality check - you have to turn off evaluation at every input for it not to be a serious problem) to "stop it here" - both things that really should be possible at any post, then returning to the last input waited for (with the last ouput put out again, possibly in the workflow. Right now, I have to put in a separate language change workflow for every. SIngle. Node - and I have to have them in every step of a multi step node. That is seriously tedious.
