A debugger session is initiated to monitor application execution. A debugger canvas corresponding to the debugger session is identified and displayed. The displayed debugger canvas includes one or more code bubbles created during a prior debugger session. The one or more code bubbles already present on the displayed debugger canvas are reused during the current debugger session. Accordingly, existing code bubbles and bubble sets are reused on a debugger canvas when entering a debug session, thus providing a more stable and manageable view for debugging an application in an integrated development environment. The code fragments in code bubbles on a debugger canvas can be analyzed, inspected, and edited during or after a debug session. Notations can also be added to a debugger canvas in the form of note bubbles and context data bubbles.
