No way to get information on FBs
Issue
The FBs in the palette are listed with only their name. The user therefore has to recall the functionality of a FB only bit its (sometimes cryptic) name.
Solution
Show a preview (ports, events, parameters) and the description text/comment for the FB in a tooltip in the palette.
Additionally one might use the comment text etc. for search queries too, such that one can search for e.g. "periodic" yielding E_CYCLE
.
A tooltip could also be added to FBs and individual ports on the canvas, explaining their functionality e.g. by their comment description.
