"Create notes" button feels intrusive

Hey! First of all, I wanted to say that I just found your project and loved the idea. I find it specially useful for labeling specific objects and visually recognizing them in the editor.

## My issue:
I have to say, much to my regret, that I wouldn't use this tool at its current state. With all due respect and with the intention of constructive criticism, its features lack of polish and user comfort. My biggest issue is, right now, that the `Create Notes` button feels incredibly annoying when I simply want to modify transforms.

That's why I suggest replacing that button with some other way to create notes. Perhaps a small button in the form of a notebook and pencil icon would be a better option, but, since the note have fundamentally nothing to do GameObjects transformation, I suggest thinking of a more proper way to access the Create Notes functionality.

## How I can contribute:
I am absolutely aware that what I'm suggesting is a quite tricky request, so I'm totally willing to think of a good solution and open a pull request. I have experience developing a few tools for the Unity Editor as well as motivation to contribute to this project, so I feel I can be of use and come up with a solution.
