Edit an argument's description. The argument actions menu (the ⚙ button) now has an "Edit description" option alongside "Edit title". Your edited description is saved and sticks — previously this could be quietly dropped.
Editing errors no longer pass silently. When an inline edit to an argument you own can't be saved — toggling a NOT, removing or editing a claim, changing or deleting a premise, switching an operator, or editing or resetting the argument — the change is rolled back and a clear error message now appears so you know it didn't take and can try again. Previously these failures could be dropped without any notice.
Removing an axiom no longer breaks the argument. Adding an axiomatic justification to a claim and then removing it now cleanly returns the claim to needing support. Previously this could drop the argument into a spurious "needs repair" state warning that an operator had the wrong number of children.
