Heres a screenshot.

Essentially, in C# the left dropdown has all the classes in a file while the right drop down has all the methods, events, properties, etc.
In VB all of my controls are in the left dropdown and I have to select them if I want to go to a particular event handler for that control.
I find it time consuming to navigate to my btnSave_Click method by first selecting btnSave in the left dropdown and then selecting Click in the right dropdown.
Is there a setting or a plugin that can change this functionality?
This really has more to do with the differences in how events are linked to control events in VB.Net versus C#, and specifically the Handles statement in VB.Net.
If you assign your methods to the control events at runtime like C# does rather than using the Handles statement in VB.Net, then all of your methods will appear in the right-hand dropdown within VB. This also applies to any member variables that you have declared as WithEvents.
