You mean you want to drag and drop any note into another tiddler and you like a handle allows you to do that! Lets see!

Question: How to delete the My Daily Micro Notes, when they become useless?
Editing the tiddler and deleting the text field does not seem appropriate to me
When you do not need your Notes anymore, go to the original tiddler with the help of the Link-to-tabs plugin and delete the MyComplexTiddlerName tiddler.
Next time you want to create new Micro Notes, simply use the Add Micro Note button and Notes tab will appear again on the sidebar.
This customization is simple, but I like its workflow
