After installing Projectify(version: 0.14.3), I noticed that the top toolbar that appears when dragging and dropping files had disappeared. After some debugging, I discovered that the root cause was that Projectify had tagged certain Tiddlers containing lingo-base function with the $:/tags/Macro tag, which caused other <<lingo>> macro to stop working. Therefore, this tag should be removed.
To put it more simply, the $:/tags/Macro tag should be removed from the two tiddlers: $:/plugins/nico/projectify/macros/todo-list and $:/plugins/nico/projectify/macros/utils.
