hi,
there are some executable statements that need a call each tick, they need a information icon or a better tooltip text.
example at physics commands, you can set a angle in degree, but if you just exec this command once (at actor click) nothing happens because this command must call permanent to reach his target.
its a tripping hazard 
(today i using physic constrains component, using properties values there in viewport for test with simulation and afterwards i want set values via blueprint and it take some time until i recognized how it works)
