The registered watch-expressions can be classified by a category (folder) for display in tree form (By default, there are no categories.).
Up to 64 categories can be created in one Watch panel. (If an attempt is made to create beyond the upper limit, a message is displayed.). |
Move the caret to the position at which you want to create and then click the toolbar button 
and enter a new category name directly from the keyboard.
Select a category name you want to edit and then click on it again and edit the category name directly from the keyboard.
Select a category you want to remove and then click the toolbar button 
.
Drag-and-drop a registered watch-expression directly onto the category you've created. That way, watch-expressions are classified by a category.
Also, the order in which categories and watch-expressions are displayed (one above or below another) can be freely changed by a drag-and-drop operation.
