Ditto here! I just upgraded to Catalina and lost functionality of the beloved but antique Plain Clip. In addition, some of the old Devon Word Service contextual menu items were unreliable. Just having a shiny replacement for those utilities make me thrilled to pay for PopClip.
As a longtime computer consultant I also have a utility addiction, like @t3kk2. PopClip is a treasure that will join DefaultFolder and Clipboard History as one of my Indispensables.
Discovery of extension snippets is icing on the cake. Oh, and a shout-out to Devon, who made me aware of PopClip among the myriad of similar utils.
