Button found again! Rated 5 out of 5 stars
I've always loved this add-on. Used it an awful lot during webdesign jobs etc.But for whatever reason, the button seem to have gone missing. I've tried everything I could thing of. Including the 'customize' option on the toolbar; the button is also not in that list of things to add). I've also tried to un-install and re-install the add-on, without effect unfortunately..Any ideas are welcome!(and sorry, only 2 stars at the moment as it's not working for me..)
EDIT: Thanks to uncoolcentral (see above) I also found my icon on the navigation toolbar. Back where it should be and a happy MeasureIt user here. 5 Stars, no doubt!
