one more issue confusing newbies:
The String Tooltip and IOBox show their content only up until the first ascii character 0. while this is understandable from the way null terminated strings in windows works it tends to confuse. (eg when understanding OSC messages)
suggestion would be replacing character 0 (or may be some other nonprintable characters as well) by some special char before displaying.
the known bug with vvvv patches not opening as soon as they contain some binary string literals is still annoying…
