Title: A way to ensure your elements appear just like you want them to
Question: A way to ensure your elements appear just like you want them to! Automatically constrains forms at runtime, at the size used in designtime! You could say this one enables constraints at default, but WITH the ability to change it in designtime any way you like. Normally, setting constraints to any maxwidth etc, will not allow you to change your mind after that, unless you change the maxwidth etc again. This one lets you change it to any size you want in designtime, while keeping the constraints enabled! It is set to Active:= True by default, which, enables the component but can be set to Active:= False which disables it.
Answer:
THellConstraints
