I would say that is the animation itself, intead following me around from the previous point, i would like that just appear below me with a shorter duration, also the style seems a little bit dated.
The main issue is that the bar moves location. It's really jarring. It would be better if it just sprouted above the text I was editing, instead of flying in to position.
Yeah, I think the animation as "move-from-previous-place" is a mistake, in that I don't think it matches our mental model (or my mental model) - I don't think of the toolbar as something that remains tied to the place I was previously editing after I stop editing there.
The transparency is fine maybe a 0.8 in the alpha channel would do the job, the color is there but the gradient is too harsh, the border line is just there with not purpose and lastly the bubble take so long to hide after i am finish with it that annoys me. Other than that is a great project, i will give a shot to the source code later. Cheers
Thanks for your feedback!
