Hi!
It would be great to add a smart suggestion (or smart search) function into empty block fields, like we used to see in google (and hundreds of other GUI's)

Small mockup:

How i imagine it should works:
There is dropdown menu appears after you typed a symbol.
Menu is filled by blocks, filtered by type of blocks (compilable with this field) and symbol you typed, just like you search through palette.
Search results updating in realtime, while you typing.
First block is selected by default, and would be inserted into field if you hit enter.
You could select other blocks with keyboard arrows.
Thanks!
