I have on more than one occasion been spending quite some time and been quite confused because I had set a patch to not be evaluated.
A clear highlighting, eg. greying out of the nodes in the sub patch, a different background color or something other, would really help letting you know if a sub patch is set to not evaluate.
+1 I know I’ve scanned a sub patch for ages looking for faulty logic when exactly this was the case. Even some indicator in the title bar would be helpful, like when a patch is locked
