ToolTip done, waiting for feedback. Any more change request?

ToolTip creation

Fixing broken diff

@ngraham Thanks for the feedback, I didn't even noticed that the button icon changes dynamically, and without you I would probably delay much more to find which code to change in that immense file. I made your requested change but I got into another bug, when the configuration is updated with split view enabled, the button stays with the old icon until the active view changes to a new one, it's a minor bug but still worth, I'll separate a time for it later.
