I thought to save some time by temporary disabling error 51455 (variable ... is declared but never used). I also temporary out-commented some code and didn't want to outcomment all variable declarations created for this code. All warnings show as errors in VO.
However, I didn't find where I could restore this. I eventually edited the .VoPrj file of the repo where somewhere it said W51455=0 which I removed.
Isn't there a built in way to see which errors/warnings are disabled (or collapsed) so you can quickly bring them back?
