During the designs for the Translate extension, we thought on making the left toolbar disappear in some circumstances. Translators are very focused on the content and the links provided by the left side toolbar are rarely needed while translating.

The idea is to hide the toolbar initially to reduce the amount of chrome and provide a cue so that users interested in it can bring it back. I created an interactive prototype to illustrate the idea.

The design has been made under the following constraints:
I wanted to share this since other tools/extensions may have faced a similar need before.
Feel free to provide any feedback, alternative solutions or info on potential problems.
