Thanks for the info Benn, and nice forum name by the way 
I can verify that yes click the arrows does save.
However requiring your users to know this somehow magically and do it as an additional step to acccess engine-essential features like the ability to import morph targets I still think is counterproductive to your goal of making the UI easier
Perhaps you need to just let people see their options and digest them over time?
People are not dumb! you dont need to treat them this way, they can handle seeing their options.
If you treat people like they can’t handle seeing all these options and try to dumb do the UI for just them you risk dumbing down the engine itself.
Why not let UE4 be its own Glorious Self and let people rise up to meet UE4, rather than lower UE4 to a minority of users who never stay as beginners for long…
but only if they learn what those little arrows mean will they ever know what their options ever were, as they are trying to learn UE4 and grow to meet UE4 in its full Power!
Let people train with the Editor, and adapt to the Editor
rather than forcing all the rest of us to deal with your attempts to dumb down the Editor, which is just an incredible inconvenience to anyone who has used UE4 for more than a week.
