It would be wonderful if the toolbar with the text formatting options was sticky, so when you were editing or creating long messages, or notes, you didn't have to scroll up every time you wanted to enable bullet points, for example.
I've attached a mockup of what this may look like via the dev tools in chrome, and was achieved as simply as adding the css attributes `position: sticky; z-index: 999;` to the `ul.redactor_toolbar` class on my local machine.
Whilst in the meantime, I could create an app that does this for me, it seems like overkill in the long-run.
