For click&pop[ removal: I started out doing this by had with the draw tool (extremely hard work), progressed to using Audacity’s Repair tool when that appeared (very hard work) - and then I got a steer from Koz that led me to using Brian Davies’ excellent ClickRepair app. It cost a little, but it saved me huge amounts of time - and produced excellent results.
