Better Tooltips, Better Documentation Please

I’m fairly new to Unreal Engine, and I have to say the tooltips and documentation are a hit or miss.

For example in my UI widget I’m working on, I binded the text to a function. In the details panel there is a boolean for “Pure”, and when you hover over it, it says “Force this to be a pure function?”. LOL. What does that even mean?

An example of the documentation needing work. I looked up “On Component Begin Overlap” for blueprints. This is what is has on the Docs page, “Event called when something starts to overlaps this component, for example a player walking into a trigger. For events when objects have a blocking collision, for example a player hitting a wall, see ‘Hit’ events.”
Well that’s all fine and dandy, but it doesn’t tell me how to use it, what each pin on the blueprint does, and doesn’t show any example of how to use it.
That’s like looking for a specific type of cat and going to a documentation page saying “It’s a cat.”

LOL.
