Have you or one of your allies ever started to build something and then walked away without ever noticing that it was still unfinished? It would be nice to distinguish unfinished units by the unit icon. But even then, you could miss something. My new
Unfinished Units Highlighter widget shows you labels on those of your units on which there is no build progress for 10 to 20 seconds if less than 1000 metal is needed to finish them (and less than 150 for allied units). I publish it hereby under the terms of the
